言，在傳送有效訊號之前，TXPA之功率需提升至要發送之功率 強度，此提升功率的過程稱之為斜升（RampUp);而在傳送完有 效訊號之後，TXPA之功率需降回最低準位，此下降功率的過程 稱之為斜降（Ramp Down )。 習知的分時多重存取（Time Division Multiple Aeeess， TDMA)系統係以一個時槽（81加）作為傳送或接收資料的單位。 任意兩個手機不可在同一時槽（亦即同時間、同頻段）發送資料， 否則會造成干擾。因此，為了避免在兩相鄰時槽之交接處造成手 機相互干擾’-般會在每個時槽之最後或最前的時段設定保護區 (Guard)且於保護區内不傳送資料。此外，由於τ〇μα系統 連續傳送多個時槽的資料，且各個時槽的傳送功率未必相同、、 此，當T D M A系統連續傳送多個時槽的資料時，需要在兩兩 時槽間的㈣區進行功率轉換’此轉換功率的過程稱為 、 (Inter_Ramn )。 曲 無=連續_S1*S2所傳送之功率強度係增加 不變比習知TDMA系統在斜升區、斜降區及間斜區的功率變= 私’白係知用線性相連的設計作為傳送功率放大器之功率控制 TW1461PA-A1 1299612 線。請參照第1A至1 c圖，絡千翌左τΓ4Λ/Γ Λ么 夫、θ不％知TDMA純之傳送功率放

控制曲線RUa、RUb及RUc皆係線性遞增，斜降控制曲線RDa、 RDb及RDc皆係線性遞減。 習知的TDMA系統係使用大容量的記憶體以儲存各種功率 強度之斜升控制曲線及斜降控·線，並採用線性運算的方式來 產生TXPA之間斜控制曲線。對於斜升區和斜降區，係在記憶體 内針對每-種功率強度存入各個對應的斜升控制曲線及斜降控 制曲線。這種作法的優點在^不需運算而能快速產生控制曲線， 缺點疋需要浪費大容量的記憶體來儲存各個對應之斜升控制曲 線及斜降控制曲線。對於間斜區，乃基於兩連續時槽的功率強度 有夕種排列組合，無法將更A量的間斜控制曲線存人記憶體，同 時考量到運算上的複雜度，故採用單純的線性運算方式來產生間 斜控制曲線。 然而，一般TX PA所消耗的電功率對於整個系統的耗電量 伯有極大的比例’尤丨是傳送的功率愈大、♦毛電量也就愈大。然 而’名知TDMA系統所採用之單純線性相連的設計，即使在系統 不傳送資料的情況下，仍須消耗相當多的電量。 TW1461PA-A1 6 1299612 【發明内容】 有4α於此’本發明的目的就是在提供一種傳送功率放大器之 二制方法及波置，不但可降低在保護區傳送功率之強度以節省耗 電更肖b以較、的5己憶體使用篁及運算時間快速地產生τχ ρΑ之 功率控制曲線，使其符合時域及頻譜上的規範。

特舉一較佳實施例，並配合所附圖式，作詳細說明如下： 【實施方式】 本發明係應用於一傳送功率放大器，傳送功率放大器係用來 控制一所欲傳送之訊號之功率，本發明之主要特徵在於在功率變 化區中產生一非線性功率控制曲線，以控制該訊號之功率變化， 藉以降低功率之消耗。功率變化區具有至少一傳送功率值κ且可 劃分為斜升區、斜降區及間斜區。本發明之功率控制曲線之產 生，主要係先根據傳送功率值κ，產生原始曲線及決定最低功率 值H。原始曲線係被水平分割為一原始曲線左區段FL以及一原 始曲線右區段FR。再根據傳送功率值κ以及最低功率值H，決 定左區段比例值SL以及右區段比例值sr。接著，根據最低功率 值H、原始曲線左區段FL以及左區段比例值SL計算出一控制曲 線左區段FL’，且根據該最低功率值η、原始曲線右區段FR以及 右區段比例值SR，計算出一控制曲線右區段FR，。最後根據控制 曲線左區段FL’以及控制曲線右區段Fr，，產生功率控制曲線， 以控制該訊號之功率變化。 功率控制曲線可分為斜升控制曲線、斜降控制曲線及間斜控 制曲線。對應於斜升區之功率控制曲線為斜升區控制曲線，對應 於斜降區之功率控制曲線為斜降區控制曲線，而對應於間斜區之 TW1461PA-A1 9 1299612 功率控制曲線為間斜區控制曲線。在第5A圖中，原始斜升左區 段FL1之左端點係為原始斜升曲線之最低點，而原始斜升右區段 FR1之右端點係為原始斜升曲線之最高點。同時，原始斜升左區 段FL 1係與原始斜升右區段FR1連續相接。在第6 A圖中，原始 ’ 斜降左區段FL2之左端點係原始斜降曲線之最高點，而原始斜降 • 右區段FR2之右端點係該原始斜降曲線之最低點。同時，原始斜 降左區段FL2係與原始斜降右區段FR2連續相接。在第4A圖中， 原始間斜左區段FLO包含一左端點以及一右端點，分別為原始間 斜左區段FLO之最高點以及最低點，而原始間斜右區段包含 春一左端點以及一右端點，分別為原始間斜右區段FR0之最低點以 及最高點。 本發明之主要精神在於利用保護區不需傳送資料的特性，將 兩兩連續時槽間的保護區（亦即間斜區）之控制曲線設計為下凹 曲線’以降低在保護區傳送功率之強度而達到省電目的。下凹曲 線的寬度可依照使用者之需要來設定，且較佳地小於時槽期間之 四分之一。 此外，同樣值付注意的是，下凹曲線係依據原始功率曲線（原 • 始曲線）所產生。原始功率曲線可以是預先儲存在記憶體中之一 多項式函數或是一餘弦函數。記憶體可具有一對照表，用來儲存 且/或記錄所有關於原始功率曲線之控制資料。在實施例中，原始 功率曲線可表示為[l+C〇S(27r *n/N)]/2，其中n&N係用來產生 原始功能曲線之控制資料。然而，本發明並不限於此，任何其他 之下凹曲線、線性或非線性曲線亦可作為本發明之原始功能 線。 儘官則後時槽的功率有多種排列組合，且任何連續 以上之時槽資料的情形皆可使用本發明，下述實施例僅將系統在 TW146IPA-A1 10 1299612 固定頻段下接續傳送兩個時槽資料之情形加以詳述。 請參照第2圖，綠示依照本發明—較佳實施例 率

=需從〇提升至第-傳送功率強度K1。斜降區之斜降控制曲 線⑽，說明在傳送完第二資料區D2的有效訊號之後，τχρΑ之 功率需從第二傳送功率強度Κ2降回最低準位卜至於間斜區之 =斜控制曲線IR，說明在第—時槽81與第二時槽82兩連續時 』的保護區P1需進行功率轉換1斜控制曲線设係以非線性 連接的方式將TXPA之功率從第—傳送功率強度κι轉換至第二 傳达功率強度K2’以形成下凹曲線，據以降低在保護㈣傳送 功率之強度。 、在第2圖中，由具有下凹形狀之間斜控制曲線瓜及線性遞 增之原始間斜控制曲線IR，所圍成之區域A，係本實施例之間斜 控制曲線IR相較於習知之間斜控制曲線IR，所節省之耗電量。此 外無哪第-傳送功率強度K1大於、等於或小於第二傳送功率 強度K2 ’本發明所採用下凹曲線之設計，皆能有效利用保護區 不為傳送資料的特性來節省耗電。 …在實施例中，本發明之在多時槽無線通訊系統之裝置之輸出 功率控制方法包括下列步驟：提供在第—時槽之第_時間點之一 第一功率值SL ;提供在相鄰於第一時槽之第二時槽之第二時 累占一 丄古 .、、 弟一功率值SR ;依據介於第一時間點與第二時間點間之 TW1461PA-A1 1299612 至少一原始功率曲線產生一輸出功率曲線，其中輸出功率曲線之 至少一輸出功率值Q係實質上小於第一功率值SL及第二功率值 SR ;以及依據輸出功率曲線調整輸出功率。 • 此外，原始功率曲線包括一第一功率曲線FL(t)及一第二功 率曲線FR(t) ’且5玄輸出功率曲線包括一第一部份⑴及一第二 邛刀FR (t)。輸出功率曲線係依據下列方程式所產生：FL，(t) = η + FL(t)*SL’，及 FR，(t) = H + FR(t)*SR，，其中，SL，= SL-H，SR，= SR-H，且H係一預設值。H可以是輸出功率曲線之最低功率值， 《可以等於功率值Q。較佳地，功率值（^大約為Q、或至少為6心 Φ 且低於第-功率值及第二功率值（例如：第一功率值及第二功率 值之較小者）。 再者，多時槽無線通訊系統可為了〇]^八通訊系統，例如： GSM、GPRS、且/或EDGE㈣。本發明多日夺槽無線通訊系統之 裝置可以為行動電話之傳送功率放大器。 睛參照第3圖，繪示依照本發明一較佳實施例的傳送功率放 大器之控制方法流程圖。首先，當傳送功率放大器在連續之第一 時槽及第二時槽傳送資料，且第一時槽及第二時槽分別具有第一 • 傳送功率值K1及第二傳送功率值K2,傳送功率放大器^控制方 法係於步驟302提供一原始曲線。原始曲線係針對時間軸水平等 分為原始左區段FL及原始右區段FR。接著，於步驟3〇4決定功 率控制曲線之最低功率值Η。在步驟306中，依據第一傳送功率 值Κ卜第二傳送功率值Κ2及最低功率值Η，計算出功率控制曲 線相對於原始曲線之左功率比例值SL及右功率比例值sr。步驟 3〇8係分別將原始左區段FL依照左功率比例值SL縮放為sl*fl 及將原始右區段FR依照右功率比例值SR縮放為SR*FR。然後， 於步驟310計算出功率控制曲線之左控制區段fl，=h+sl*fl及 TW1461PA-A1 12 1299612 右控制區段FR，=H+SR*FR，而於步驟312產生功率控制曲線。 依據上述步驟，可逐一產生功率控制曲線之間斜區控制曲 線、斜升區控制曲線及斜降區控制曲線。尤其，本發明較佳實施 . 例之傳送功率放大器之控制方法，係產生具有下凹形狀之間斜控 制曲線，用以控制傳送功率放大器之間斜區功率強度，使間斜區 功率強度從第一傳送功率值K1轉換至第二傳送功率值K2;更產 生斜升控制曲線，用以控制傳送功率放大器之斜升區功率強度， 使斜升區功率強度從最低功率值H提升至第一傳送功率值κι ; 以及產生斜降控制曲線，用以控制該傳送功率放大器之斜降區功 率強度，使斜降區功率強度從第二傳送功率值K2降回至最低功 率值Η。 凊參照第4Α及4Β圖，繪示依照本發明一較佳實施例之原 始間斜曲線及間斜控制曲線之示意圖。功率控制曲線之間斜區控 制曲線具有下凹形狀。產生間斜控制曲線之方法如下··首先，提 供原始間斜曲線，水平等分為原始間斜左區段FL〇及原始間斜右 區段FRO。如第4A圖所示，原始間斜左區段FL〇與原始間斜右 區段FRO之曲線外形未必需要對稱，僅需符合時域及頻譜上的規 • 範範圍，不致造成相鄰兩頻道的資料干擾即可。原始間斜左區段 FLO係從單位功率值非線性遞減至〇功率，而原始間斜右區段fr〇 係從0功率非線性遞增至單位功率值。接著，決定功率控制曲線 之最低功率值Η。依據第一傳送功率值K1、第二傳送功率值K2 及最低功率值Η，計算出間斜控制曲線相對於原始間斜曲線之左 間斜功率比例值SL0=K1-H及右間斜功率比例值SR〇=K2_H。再 分別將原始間斜左區段FL1依照左間斜功率比例值sl〇縮放為 SL0*FL0及將原始間斜右區段fro依照右間斜功率比例值 縮放為SR0*FR0。然後，計算左間斜控制區段 TW1461PA-A1 13 1299612 FL0’=(SL0/2N)*(FL0*2N)及右間斜控制區段 FR0’=H+(SR0/2N)*(FR0*2N)。最後，如第4B圖所示，即可產生 具有下凹形狀之間斜控制曲線，並藉由電壓、電流或功率之控制 ， 輸入以有效控制傳送功率放大器於間斜區之功率強度。依照本發 明較佳實施例的傳送功率放大器之控制方法所產生之間斜控制 • 曲線，不會有間斜控制曲線與前一個時槽或後一個時槽的功率控 制上不連續的問題，也不會有左間斜控制區段與右間斜控制區段 的功率控制上不連續的問題。 在各種實施例中，前一及後一時槽可包括不同之調變類型 馨 （例如：第一時槽包括一第一調變類型而第二時槽包括一不同於 第一調變類型之第二調變類型）。當介於第一及第二時槽（例如 在保護區）之輸出功率低於一臨界值，從第一調變類型切至第二 調變類型之瞬變電流會發生。例如，第一時槽可使用GMSK調變 而第二時槽可使用8PSK調變，且臨界值可介於H及兩時槽中較 低之輸出功率值。在一實施例中，關鍵值大約為Η + (ρ*Δ)，△ 為Η與兩時槽中較低之輸出功率值之差，且ρ為一個約為〇·25 至〇·5之值。 籲 請參照第5Α及5Β圖，繪示依照本發明一較佳實施例之原 始斜升曲線及斜升控制曲線之示意圖。產生斜升控制曲線之方法 如下··首先’提供原始斜升曲線，水平等分為原始斜升左區段FL1 及原始斜升右區段FR1。如第5A圖所示，原始斜升左區段FL1 及原始斜升右區段FR1之曲線外形未必需要對稱，僅需符合時域 及頻譜上的規範範圍，不致造成相鄰兩頻道的資料干擾即可。原 始斜升左區段FL1係從〇功率非線性遞增，原始斜升右區段FR1 係非線性遞增至單位功率值，且原始斜升左區段FL1與原始斜升 右區段FR1連續相接。接著，依據第一傳送功率值K1及最低功 TW1461PA-A1 14 1299612 率值Η，計算出斜升控制曲線相對於原始斜升曲線之左斜升功率 比例值SL1及右斜升功率比例值SR1。在此斜升區中，左斜升功 率比例值SL L及右斜升功率比例值SR1相等，亦即 SL1=SR1=K1-H。再分別將原始斜升左區段FL1依照左斜升功率 比例值SL1縮放為SL1*FL1及將原始斜升右區段FR1縮放為 SRI *FR1。然後，計算左斜升控制區段 FL1，=H+(SL 1/2n：)'FX 1 及右斜升控制區段FR1’=H+(SR1/2n)*(FR1*2n)。最後，如第5Β 圖所示，即可 產生非線性之斜升控制曲線，並藉由電壓、電 流或功率之控制輸入以有效控制傳送功率放大器於斜升區之功 率強度。依照本發明較佳實施例的傳送功率放大器之控制方法所 產生之斜升控制曲線，不會有斜升控制曲線與後一個時槽的功率 控制上不連續的問題，也不會有左斜升控制區段與右斜升控制區 段的功率控制上不連續的問題。 清參照第6Α及6Β圖’繪不依照本發明一較佳實施例之原 始斜降曲線及斜降控制曲線之不意圖。產生斜降控制曲線之方法 如下·首先，提供原始斜降曲線，水平等分為原始斜降左區段FL2 及原始斜降右區段FR2。如第6Α圖所示，原始斜降左區段 及原始斜降右區段FR2之曲線外形未必需要對稱，僅需符合時域 及頻譜上的規範範圍，不致造成相鄰兩頻道的資料干擾即可。原 始斜降左區段FL係從單位功率值非線性遞減，原始斜降右區段 FR係非線性遞減至〇功率，且原始斜降左區段fl係與原始斜降 右區段FR連續相接。接著，依據第二傳送功率值Κ2及最低功 率值Η，計算出左斜降功率比例值SL2及右斜降功率比例值 SR2。在此斜降區中，左斜降功率比例值sl2及右斜降功率比例 值SR2相等’亦即SR2SL2=SR2=K2_H。再分別將原始斜降左區 段FL2依照左斜降功率比例值SL2縮放為SL2*FL2及將原始斜 TW1461PA-A1 15 1299612 降右區段FR2依照右斜降功率比例值SR2縮放為SR2*FR2。然 後，計算左斜降控制區段FL2’=H+(SL2/2N)*(FL2*2N)及右斜降控 制區段FR2’=H+(SR2/2N)*(FR2*2N)。最後，如第6B圖所示，即 可產生非線性之斜降控制曲線，並藉由電壓、電流或功率之控制 輸入以有效控制傳送功率放大器於間斜區之功率強度。依照本發 明較佳實施例的傳送功率放大器之控制方法所產生之斜降控制 曲線，不會有斜降控制曲線與前一個時槽的功率控制上不連續的 問題，也不會有左斜降控制區段與右斜降控制區段的功率控制上 不連續的問題。 請參照第7圖，繪示依照本發明一較佳實施例之記憶體之方 塊圖。記憶體720包括原始曲線左區段對照表721、原始曲線右 區段對照表722、左區段比例值對照表723、右區段比例值對照 表724及最低功率值對照表725。原始曲線左區段對照表721係 用來儲存數個原始曲線左區段，且每一原始曲線左區段係對應於 一個傳送功率值。原始曲線右區段對照表722係用來儲存數個原 始曲線右區段，且每一原始曲線右區段係對應於一個傳送功率 值。最低功率值對照表725係用來儲存數個最低功率值，且每一 最低功率值係對應於一傳送功率值。左區段比例值對照表723係 用來儲存數個左區段比例值，且每一左區段比例值係對應於一傳 送功率值以及一最低功率值。右區段比例值對照表724係用來儲 存數個右區段比例值，其中每一右區段比例值係對應於一傳送功 率值以及一最低功率值。 有關實際運算上的作法，係分別將各個計算參數，最低功率 值Η、左功率比例值SL、右功率比例值SR、原始左區段FL及 原始右區段FR，在不同功率下之對應值，建立成數組儲存表格， 而將FL對照表721、FR對照表722、SL對照表732、SR對照表 TW1461PA-A1 16 1299612 724及Η對照表725儲存於記憶體720内。當使用不同的輸出功 率強度，系統可以藉由查表的方式，快速找到所對應的設定值。 在記憶體使用上，相較於習知TDMA系統需將各種功率強度控制 曲線存入記憶體内的作法，本發明採用將原始曲線比例縮放的方 式所需之記憶體使用量明顯減少。在運算速度上，為了避免原始 左區段FL及原始右區段FR需採用之Μ莫擬浮點數（float point) 的乘法讓整數型（fixed point)嵌入式系統耗費數十個運算指令， 儲存表格上有關原始左區段FL及原始右區段FR之内容係記錄原 始左區段FL及原始右區段FR分別乘以2的N次方後的值（亦 即FL—TABLE=FL*2N及FR一TABLE=FR*2N)。當計算左控制區段 FL’及右控制區段FR’時，可單純以移位方式處理（亦即 FL，=H+SL*(FL_TABLE)右移 Nbit)及 FR，=H+SR*(FR_TABLE) 右移Nbit)，以節省運算量。藉此，運算上即可採用二進位移位 方式來達成浮點數乘法的目的，而克服浮點數繁雜的乘法計算。 相較於習知TDMA系統需將控制曲線每一點作線性運算的作 法，本發明將整個原始曲線作整數相乘位移的計算更可快速算出 控制曲線。此外，系統亦可辅以積體電路作成輔助計算單體 (co-processor )來進行整數相乘位移的運算，更能節省控制曲線 的運算量及運算時間。 本發明上述實施例所揭露之傳送功率放大器之控制方法，可 控制TXPA在轉換功率強度時作非線性連接，以達到省電目的； 更進一步提出特殊的運算技巧，不但能以較少的記憶體使用量及 運算時間，簡易且快速地產生TXPA之功率控制曲線，亦可使功 功率變化區之控制曲線保有特定外形，使其符合時域及頻譜上的 規範。

Field of the Invention This invention relates to a method and apparatus for controlling a transmission power amplifier, and more particularly to a method and apparatus for protecting a transmission power amplifier for use in a wireless communication system. . [Prior Art] The wireless communication system transmits data to the remote end through the atmosphere, and the power of the signal is enhanced by a TX Power Amplifier (TXPA) to prevent the signal from being attenuated until it reaches the remote destination. The noise. In general, before transmitting a valid signal, the power of the TXPA needs to be increased to the power level to be transmitted. This process of boosting power is called rampup (RampUp); after the valid signal is transmitted, the power of the TXPA needs to be reduced. The lowest level, this process of reducing power is called ramp down. The conventional Time Division Multiple Aeeess (TDMA) system uses a time slot (81 plus) as a unit for transmitting or receiving data. Any two mobile phones cannot send data in the same time slot (that is, at the same time, in the same frequency band), otherwise it will cause interference. Therefore, in order to avoid mutual interference between the two adjacent time slots, the Guard will be set at the last or first time of each time slot and no data will be transmitted in the protected area. In addition, since the τ〇μα system continuously transmits data of a plurality of time slots, and the transmission power of each time slot is not necessarily the same, when the TDMA system continuously transmits data of a plurality of time slots, it is required to be between the two slots. (4) Power conversion for the area 'The process of converting power is called (Inter_Ramn).曲无=Continuous _S1*S2 The power intensity transmitted by the _S1*S2 is increased. The power of the conventional TDMA system in the ramp-up zone, the ramp-down zone and the inter-slope zone is changed. Power amplifier power control TW1461PA-A1 1299612 line. Please refer to the figures 1A to 1c. The 翌 翌 Γ Γ Λ Λ 、 θ θ θ θ θ θ θ θ θ θ θ θ T T T T T T T T T T T T T T T T T T T T T T T T T T T T In the second figure, the power intensity transmitted by the slots S1 and S2 is increased, and the line of the oblique control curve is increased, and the power intensity is between the transmission powers of the two consecutive time slots. In 1B@中, the power transmitted by the slots S1 and S2 in two consecutive time slots is strong. =: The curve 1Rb is a linearly decreasing straight line whose power intensity is between the transmission power of the two consecutive slots. In the lc diagram, the power intensity transmitted by the slots 81 and 82 is constant during the two consecutive time slots, and the inter-tilt control curve IRe is a horizontal straight line. As for the ramp control curves RUa, RUb and RUc are linearly increasing, the ramp down control curves RDa, RDb and RDc are linearly decreasing. The conventional TDMA system uses a large-capacity memory to store ramp-up control curves and ramp-down control lines of various power intensities, and uses a linear operation to generate a skew control curve between TXPAs. For the ramp-up zone and the ramp-down zone, each corresponding ramp-up control curve and ramp-down control curve are stored in the memory for each power intensity. The advantage of this method is that the control curve can be quickly generated without calculation, and the disadvantage is that a large-capacity memory needs to be wasted to store each corresponding ramp-up control curve and ramp-down control curve. For the oblique zone, based on the power intensity of the two consecutive time slots, there is a combination of the same kind of time, and it is impossible to store the more oblique control curve of the A amount in the memory, and at the same time consider the computational complexity, so the simple linear operation is adopted. The way to generate the skew control curve. However, the power consumed by a typical TX PA has a large proportion of the power consumption of the entire system. In particular, the greater the power delivered, the greater the power of the ♦. However, the purely linear design of the well-known TDMA system consumes a considerable amount of power even when the system does not transmit data.

The main feature of the present invention is to generate a nonlinear power control curve in the power variation region to control the power variation of the signal, thereby reducing the power. Consumption. The power change zone has at least one transmit power value κ and can be divided into a ramp-up zone, a ramp-down zone, and an inter-slope zone. The power control curve of the present invention is mainly generated based on the transmission power value κ to generate an original curve and determine a minimum power value H. The original curve is horizontally divided into a left curve FL of the original curve and a right segment FR of the original curve. Further, based on the transmission power value κ and the lowest power value H, the left sector scale value SL and the right sector scale value sr are determined.

The raw power curve can be a polynomial function or a cosine function pre-stored in the memory. The memory can have a look-up table for storing and/or recording all control data regarding the raw power curve. In an embodiment, the original power curve can be expressed as [l + C 〇 S (27r * n / N)] / 2, where n & N is used to generate control data for the original functional curve.

As shown in Fig. 2, the adjacent first time slot S1: time slot: 2 sets the last time period as the first protection zone ρι and the second protection zone 卩 2, respectively, only in the first data zone (1) and The second data area (7) transmits the data, and the data is not transmitted in the protected area P1 and the second protected area P2. The ramp-up control curve RU of the ramp-up area indicates that τχρΑ = needs to be raised from 〇 to the first-transmitted power level K1 before transmitting the valid signal of the first data area 〇1. The ramp-down control curve (10) of the oblique drop zone indicates that after the effective signal of the second data zone D2 is transmitted, the power of τχρΑ needs to be reduced from the second transmit power intensity Κ2 to the lowest level to the oblique slope control curve. IR, indicating that when the first-time slot 81 and the second time slot 82 are continuous, the protection zone P1 needs to perform power conversion. The oblique control curve sets the power of the TXPA from the first transmission power intensity λι in a non-linear connection manner. Switching to the second communication power intensity K2' to form a concave curve, thereby reducing the intensity of the transmission power in the protection (4).

The curve produces an output power curve, wherein at least one output power value Q of the output power curve is substantially smaller than the first power value SL and the second power value SR; and the output power is adjusted in accordance with the output power curve. In addition, the original power curve includes a first power curve FL(t) and a second power curve FR(t)' and the 5th output power curve includes a first portion (1) and a second file FR (t) . The output power curve is generated according to the following equation: FL, (t) = η + FL(t) * SL', and FR, (t) = H + FR(t) * SR, where SL, = SL- H, SR, = SR-H, and H is a preset value. H can be the lowest power value of the output power curve, "can be equal to the power value Q. Preferably, the power value (^ is approximately Q, or at least 6 Φ and is lower than the first power value and the second power value (eg, the smaller of the first power value and the second power value). The multi-time slot wireless communication system can be used for the communication system, for example: GSM, GPRS, and/or EDGE (4). The device of the multi-day slot wireless communication system of the present invention can be a power amplifier for mobile phones. 3 is a flow chart showing a control method of a transmission power amplifier according to a preferred embodiment of the present invention. First, when a transmission power amplifier transmits data in a continuous first time slot and a second time slot, and the first time slot and The second time slot has a first transmit power value K1 and a second transmit power value K2, respectively, and the transmit power amplifier control method provides an original curve in step 302. The original curve is equally divided into the original left segment for the time axis level. FL and the original right sector FR. Next, the lowest power value Η of the power control curve is determined in step 〇 4. In step 306, the second transmission power value Κ2 and the lowest power value Κ are determined according to the first transmission power value. Calculation The power control curve is proportional to the left power ratio value SL and the right power ratio value sr of the original curve. Step 3〇8 respectively scales the original left segment FL according to the left power ratio value SL to sl*fl and the original right segment FR According to the right power ratio value SR, it is scaled to SR*FR. Then, in step 310, the left control section fl of the power control curve is calculated, =h+sl*fl and TW1461PA-A1 12 1299612 right control section FR,=H+ SR*FR, and a power control curve is generated in step 312. According to the above steps, the ramp control curve, the ramp region control curve and the ramp down region control curve between the power control curves can be generated one by one. In particular, the present invention is preferably implemented. The control method of the transmission power amplifier is to generate a skew control curve with a concave shape for controlling the power intensity of the oblique region between the transmission power amplifiers, so that the power intensity of the oblique slope region is converted from the first transmission power value K1 to the first a transmission power value K2; a ramp control curve is generated to control the power intensity of the ramp power of the transmission power amplifier, so that the power intensity of the ramp region is raised from the lowest power value H to the first transmission power value κι; A ramp-down control curve is generated for controlling the power level of the ramping region of the transmitting power amplifier, so that the power intensity of the ramping region is reduced from the second transmitting power value K2 to the lowest power value Η. 凊 Referring to Figures 4 and 4, drawing A schematic diagram of an original skew curve and a skew control curve according to a preferred embodiment of the present invention. The oblique zone control curve between the power control curves has a concave shape. The method for generating the skew control curve is as follows: The oblique curve is horizontally divided into the original oblique left segment FL〇 and the original oblique oblique segment FRO. As shown in Fig. 4A, the curve between the original oblique left segment FL〇 and the original oblique oblique segment FRO The shape does not necessarily need to be symmetrical, and only needs to conform to the scope of the time domain and the spectrum, so as not to cause interference between adjacent channels. The original oblique left section FLO is nonlinearly decremented from the unit power value to the 〇 power, while the original slant right section fr 非线性 is nonlinearly increased from 0 power to the unit power value. Next, the lowest power value Η of the power control curve is determined. According to the first transmission power value K1, the second transmission power value K2 and the lowest power value Η, the left oblique power ratio SL0=K1-H and the right oblique power ratio of the skew control curve with respect to the original oblique curve are calculated. The value SR〇=K2_H. Then, the original oblique left segment FL1 is scaled to SL0*FL0 according to the left oblique power proportional value sl〇, and the original oblique right segment fro is scaled to SR0*FR0 according to the right oblique power ratio value. Then, calculate the left skew control section TW1461PA-A1 13 1299612 FL0'=(SL0/2N)*(FL0*2N) and the right skew control section FR0'=H+(SR0/2N)*(FR0*2N) . Finally, as shown in Fig. 4B, a skew control curve with a concave shape can be generated and controlled by voltage, current or power to effectively control the power intensity of the transmission power amplifier in the inter-slope region. The oblique control curve generated by the control method of the transmission power amplifier according to the preferred embodiment of the present invention does not have the problem that the skew control curve is discontinuous with the power control of the previous time slot or the latter time slot, There is no problem of discontinuity in power control between the left skew control section and the right skew control section. In various embodiments, the first and subsequent slots may include different modulation types (eg, the first time slot includes a first modulation type and the second time slot includes a different one than the first modulation type) Two modulation types). When the output power between the first and second time slots (e.g., in the protection zone) is below a threshold, a transient current that is switched from the first modulation type to the second modulation type occurs. For example, the first time slot can use GMSK modulation and the second time slot can use 8PSK modulation, and the threshold can be between H and the lower output power value of the two time slots. In one embodiment, the key value is approximately Η + (ρ*Δ), Δ is the difference between the lower output power values of Η and the two time slots, and ρ is a value of approximately 〇·25 to 〇·5 . Referring to Figures 5 and 5, a schematic diagram of an initial ramp-up curve and a ramp-up control curve in accordance with a preferred embodiment of the present invention is shown. The method of generating the ramp-up control curve is as follows: First, the original ramp-up curve is provided, and the horizontal equal-division is divided into the original ramp-up left section FL1 and the original ramp-up right section FR1. As shown in Fig. 5A, the curve shape of the original ramp-up left section FL1 and the original ramp-up right section FR1 does not necessarily need to be symmetrical, and only needs to conform to the specification range of the time domain and the spectrum, so as not to cause data interference of adjacent two channels. Just fine. The original ramp-up left section FL1 is nonlinearly increasing from the 〇 power, and the original ramp-up right section FR1 is nonlinearly increased to the unit power value, and the original ramp-up left section FL1 is continuously connected to the original ramp-up right section FR1. . Then, based on the first transmission power value K1 and the lowest power TW1461PA-A1 14 1299612 rate value Η, the left ramp power ratio value SL1 and the right ramp power ratio value SR1 of the ramp control curve with respect to the original ramp curve are calculated. In this ramp-up region, the left ramp power ratio value SL L and the right ramp power scale value SR1 are equal, that is, SL1 = SR1 = K1 - H. Then, the original ramp-up left section FL1 is scaled to SL1*FL1 according to the left ramp-up power ratio value SL1 and the original ramp-up right section FR1 is scaled to SRI*FR1. Then, the left ramp control section FL1, = H + (SL 1/2n:) 'FX 1 and the right ramp control section FR1' = H + (SR1/2n) * (FR1 * 2n) are calculated. Finally, as shown in Figure 5, a nonlinear ramp-up control curve can be generated and controlled by voltage, current, or power to effectively control the power level of the transmit power amplifier in the ramp region. The ramp-up control curve generated by the control method of the transmission power amplifier according to the preferred embodiment of the present invention does not have the problem of discontinuity in the power control of the ramp-up control curve and the latter slot, nor does it have a left-inclined rise. The problem of discontinuity in power control between the control section and the right ramp-up control section. Referring to Figures 6 and 6, the original ramp-down curve and the ramp-down control curve are not intended to be in accordance with a preferred embodiment of the present invention. The method of generating the ramp-down control curve is as follows: First, the original ramp-down curve is provided, and the horizontal equalization is divided into the original ramp-down left section FL2 and the original ramp-down right section FR2. As shown in Fig. 6, the curve shape of the original obliquely descending left section and the original obliquely falling right section FR2 does not necessarily need to be symmetrical, and only needs to conform to the specification range of the time domain and the spectrum, so as not to cause data interference of adjacent channels. can. The original ramp-down left section FL is nonlinearly decremented from the unit power value, and the original ramp-down right section FR is nonlinearly decremented to the 〇 power, and the original ramp-down left section fl is continuous with the original ramp-down right section FR. Pick up. Next, based on the second transmission power value Κ2 and the lowest power value Η, the left ramp down power ratio value SL2 and the right ramp down power ratio value SR2 are calculated. In this ramp down region, the left ramp down power ratio value sl2 and the right ramp down power scale value SR2 are equal', that is, SR2SL2 = SR2 = K2_H. Then, the original ramp-down left section FL2 is scaled to SL2*FL2 according to the left ramp-down power ratio value SL2, and the original ramp TW1461PA-A1 15 1299612-down right section FR2 is scaled to SR2*FR2 according to the right ramp-down power ratio value SR2. . Then, the left ramp down control section FL2' = H + (SL2 / 2N) * (FL2 * 2N) and the right ramp down control section FR2' = H + (SR2 / 2N) * (FR2 * 2N) are calculated. Finally, as shown in Fig. 6B, a nonlinear ramp-down control curve can be generated and controlled by voltage, current or power to effectively control the power level of the transmit power amplifier in the inter-slope region. The ramp-down control curve generated by the control method of the transmission power amplifier according to the preferred embodiment of the present invention does not have the problem of discontinuity in the power control of the ramp-down control curve and the previous time slot, and there is no left ramp down. The problem of discontinuity in power control between the control section and the right ramp down control section. Referring to Figure 7, a block diagram of a memory in accordance with a preferred embodiment of the present invention is shown. The memory 720 includes an original curve left section comparison table 721, an original curve right section comparison table 722, a left section scale value comparison table 723, a right section scale value comparison table 724, and a lowest power value comparison table 725. The original curve left segment comparison table 721 is used to store a number of original curve left segments, and each original curve left segment corresponds to a transmission power value. The original curve right segment comparison table 722 is used to store a number of original curve right segments, and each original curve right segment corresponds to a transmission power value. The lowest power value comparison table 725 is used to store a number of lowest power values, and each of the lowest power values corresponds to a transmitted power value. The left segment scale value comparison table 723 is used to store a plurality of left segment scale values, and each left segment scale value corresponds to a transmission power value and a lowest power value. The right segment scale value comparison table 724 is used to store a number of right segment scale values, wherein each right segment scale value corresponds to a transfer power value and a lowest power value. Regarding the actual operation, the corresponding values of the respective calculation parameters, the lowest power value Η, the left power ratio value SL, the right power ratio value SR, the original left segment FL, and the original right segment FR at different powers are respectively obtained. The array storage table is created, and the FL comparison table 721, the FR comparison table 722, the SL comparison table 732, the SR comparison table TW1461PA-A1 16 1299612 724, and the Η comparison table 725 are stored in the memory 720. When using different output power intensities, the system can quickly find the corresponding set value by looking up the table. In the use of memory, the conventional TDMA system requires various power intensity control curves to be stored in the memory. The present invention significantly reduces the amount of memory used to scale the original curve. In terms of operation speed, in order to avoid the original left segment FL and the original right segment FR, the multiplication of the float point is required to make the fixed point embedded system consume dozens of operation instructions. The content on the storage table regarding the original left segment FL and the original right segment FR records the value of the original left segment FL and the original right segment FR multiplied by 2 to the Nth power (ie, FL_TABLE=FL*). 2N and FR-TABLE=FR*2N). When calculating the left control section FL' and the right control section FR', it can be handled simply by shifting (ie, FL, =H+SL*(FL_TABLE) shifting Nbit right) and FR,=H+SR*( FR_TABLE) Move Nbit to the right to save computation. In this way, the binary bit shift mode can be used to achieve the purpose of floating point multiplication, and the complicated multiplication calculation of floating point numbers is overcome. Compared with the conventional TDMA system, each point of the control curve needs to be linearly operated. The present invention can calculate the control curve by calculating the integer multiplication displacement of the entire original curve. In addition, the system can also be used as an auxiliary calculation unit (co-processor) to perform integer multiplication and displacement calculations, which can save the calculation amount and calculation time of the control curve. The control method of the transmission power amplifier disclosed in the above embodiments of the present invention can control the TXPA to make a non-linear connection when converting the power intensity to achieve the purpose of power saving; further propose a special operation technique, which can not only use less memory. The usage and operation time can easily and quickly generate the power control curve of TXPA, and the control curve of the power power change zone can also maintain a specific shape, so that it conforms to the time domain and spectrum specifications.

Dotted line 1〇12_1〇14 (using 8PSK modulation in time slot 1), dotted line ι〇22 (using GMSK in the oblique zone 9〇〇 • modulation), and dashed line 1032_1〇34 (using GMSK modulation in time slot 2) It constitutes the timing protection of the hybrid modulation wireless communication system, and its parameters are defined by the GSM/GPRS/EDGE specifications. According to the timing protection defined by the GSM/GpRS/EDGE specification, the per-output power value will be less than the _preset maximum power value or exceed a preset minimum power value (for example: line segment 1〇12, 1〇14, 1 〇22,1〇32 and 1034). For s, the output power value (from the solid line 1 〇 42, 1 〇 4 bucket and draw) Do not b) when the juice exceeds the juice (by the dotted line 1〇12, 1〇14, 1〇22, and drawn) . Referring to Figure 9, a schematic diagram of a conventional hybrid modulation (e.g., EDGE) wireless communication system is shown. It is conventional to control the power value in the interleaved zone 9 to increase the power value to B in a linear point by point manner. As shown in Fig. 9, the upper unit is connected to the power value eight and the power value 8 in the interleaved area to form a linear power line segment. However, &&; using conventional methods as shown in Figs. 11A-11B, a transient current will be generated in the inter-slope region. Figure Β-11 shows the high-power transient current for the known mixed-modulation wireless communication pure output power in the oblique zone, showing the transient current generated at different frequencies and at different times 11〇〇 . As shown in Fig. uA, in the skew, 叩〇, the transient indication 1100a_b exceeds the timing guard m〇a_b (dashed line). The partial transient indication 1HH)a_b exceeds the timing guard (10)a_b, which may be provoked by adjacent channels used by other mobile communication devices (eg, mobile phones). In addition, as shown in FIG. 11B, a transient current peak 1100 having a frequency of 〇·4ΜΗζ TW1461PA-A1 19 1299612 is generated from the transmission channel in the oblique region _. Figure 11B is a graph showing the power curve expressed in terms of a frequency function. We can therefore determine the portion of the high transient current 1100 that will occur in the diagonal line (e.g., in the interslope zone 900). As shown in Figure 11B, the transient/current peak power value is greater than -20dBm beyond the normal tolerance. In order to solve the above problems that may occur in the transient current, the present invention provides a method and apparatus for forming a concave curve in an oblique region so that the instantaneous current power of the oblique region does not exceed a predetermined maximum value (for example, The maximum timing/power protection). For example, in one embodiment, the present invention is directed to a method of reducing the instantaneous current between ramps in a communication protocol, including the following steps: _ 1 - determining the output in the inter-slope region based on the concave power curve The power value (for example, for all time points) such that some power values in the inter-slope region are lower than the first-time slot immediately before the inter-slope region and/or second immediately after the inter-slant region The power value of the signal of the time slot. The power curve is not a straight line of the conventional oblique curve as shown in Figure 9, although it may also include one or more portions that are substantially linear segments. 2. Configure or generate a concave curve such that the lowest point (e.g., the lowest power value) occurs substantially at the point where the _ current will occur and below the threshold value (e.g., a predetermined power value). In general, the lowest point of the concave curve occurs in the center of the oblique zone. • 3. Use at least one original curve to create a concave curve. In a specific embodiment, the concave curve includes the original curves (1) and fr(1). FIG. 12 is a graph showing the effect of high power transient current on the output power of the hybrid modulation wireless communication system in the oblique region according to a preferred embodiment of the present invention, and plotting the output power expressed as a function of time. Immediately before the skew zone _, the output power curve 1240 has a first power value of about -6 dBm in time slot 1 (using 8PSK modulation). Immediately after the skew zone _, the output power curve is measured at time slot 2 with a second power value of approximately 〇 dBm (using modulation). In the inter-slope region _, the output power curve 124〇 is generally concave, and has a second (or TW1461PA-A1 20 1299612 left) increase segment 1222, a second (or right) increase segment 1224, and A minimum power value of approximately _3 〇 dBm. In some embodiments, the threshold of the lowest point 1223 of the ramp 900 between the power curve 1240 can be set to _6 dBm, _i 〇 dBm, or 20 dBm, or even lower than the interslope region 122 〇 The lower of the first and second power values before or after. Assuming that the threshold is _2() as shown in Figure 12, the lowest point (minimum power value 1225) is clearly less than this threshold. Figure 13A-1 shows the output power and output frequency functions and the output power-time function at a particular output frequency, respectively, in accordance with a preferred embodiment of the present invention, thereby showing the results produced by the present invention. Figure 13A shows the first output power curve as a function of frequency, while Figure 13B shows the second output power curve as a function of time at a given frequency (here the transient current is δ = 0.4 MHz). On the first output power curve, the power value of the transient current 136 〇 a 位 is located at +/- 〇 · 4 分别 and is clearly lower than the power value defined by the guard lu 〇 a — bm. Therefore, as shown in Figures 13A-13B, the output power curve in the inter-slope region 9〇〇 has a lower peak (its power value is less than 2〇dBm), which is compared to the UB diagram. The peak of the conventional system (its power value is higher than a 20 dBm). Thereby, any higher-frequency transient currents caused by interference occurring in adjacent channels can be reduced or avoided. Figure 14 is a block diagram showing the action unit to which the present invention is applied. As shown in Fig. 14, in addition to the above-described power control device 800, controller 839, and power amplifier 831, the mobile unit 83 further has a wireless control module 85 and a transient period estimator 87. The wireless control module 85, the power control device 800, the transient period estimator 87, or the controller 839 may be implemented in whole or in a microprocessor or in one or more physical layers (eg, Body circuit). It should be noted that the controller 839 can (1) adjust the output power of the power amplifier according to the output power curve, and can also (2) control the switching of the power value/modulation type between adjacent time slots (for example, from the first The first modulation type of the time slot is switched to the second modulation type of the second time slot). For the switching of the TW1461PA-A1 21 1299612 control modulation type, the controller 839 may further include a general purpose output (GPO) device or a three-wire command unit. In the TDMA communication system, the wireless control module 85 receives the signal from the base station 81 and outputs a control signal (e.g., CONTROL in Fig. 14) to the power copying device 800. The control signal includes all of the characteristics of the slot at each time slot of the subsequent data frame. The feature data may include the power value of the slot at each time of the data frame, the position of each time slot (from which the position can be indicated, determined or set between adjacent slots), and/or each time slot of the data frame. Modulation type. For example, the control signal informs the power device 8 that the required power value of the slot 1 should be A (about -6 dBm) and the required power value of the time slot 2 should be B (about 0 dBm). ). The power control unit 8 then configures or produces an output power curve between the time slot 1 and the time slot 2 between the slots 2. Also, at least one of the output power values of the output power curve is substantially less than the power values A and B. After the output power curve is generated, the transient period estimator 87 more estimates and/or determines during the transients within the output power curve (and during the inter-slope region 900) that all of the output power is less than a predetermined threshold. In some embodiments, the transient period includes the period or time at which the lowest point of the output power curve occurs. Thus, during transients of the output power curve, controller 839 switches the control output power value of power amplifier 831 and switches from power value A to power value B (and/or can switch from the first modulation type to the second modulation) Variable type). Therefore, in addition to controlling the power value conversion between slots, in the EDGE communication system, the mobile unit 83 can also be used to control the modulation type conversion between time slots. For example, the control signal can inform the power control device 8 that the desired modulation type of the slot is 8PSK at time 12 and the desired modulation type for time slot 2 is GMSK. The power control unit 8 then configures or produces an output power curve between the time slot i and the time slot 9 between the slots 2. After the output power curve is generated, the transient period estimator 87 estimates and/or determines that during the transient of the TW1461PA-A1 22 1299612 constant output power curve (and in the inter-slope region 900), all of the output power systems are less than one pre- Set the threshold. In some embodiments, the transient period includes the period or time at which the lowest point of the output power curve occurs. Therefore, during the transient of the output power curve, the controller 839 can switch the power amplifier 83 from the 8pSK modulation type (time slot 1) to the GMSK modulation type (time slot 2). Therefore, by switching the power value/modulation type during the transient, the transient current generated by the power value/modulation type switching will occur during the transient, and can be controlled by the above-described method and apparatus for reducing power of the present invention. . As shown in Fig. 13, the occurrence of transient current refers to a sudden increase and decrease in the output power value to form a peak with a relatively high power value. In the present invention, the output power value during the (four) variation period may be the lowest power value or lower than the -threshold value, so the peak power value generated by the transient current can be controlled and will not be controlled regardless of any sudden increase in the material. Will exceed the timing protection. In the above, the present invention has been disclosed in the above-described preferred embodiments, and it is not intended to limit the invention to those skilled in the art, and various modifications may be made without departing from the scope of the invention. And the refinement of the invention is therefore defined by the scope of the appended claims.
