請參考第2圖，第2圖所繪示的係為依據本發明之一第一實施例的天線分集系統200的簡化方塊示意圖，其中天線分集系統200係為一多輸入多輸出(Multi-Input Multi-Output，MIMO)天線系統。如第2圖所示，天線分集系統200包含有：一第一天線210、一第二天線220、一第一射頻電路230、一第二射頻電路240以及一訊號處理單元250。第一射頻電路230以及第二射頻電路240係分別耦接於第一天線210以及第二天線220，其中第一射頻電路230以及第二射頻電路240係分別用來操作在一第一頻道以及一第二頻道上，以及訊號處理單元250係耦接於第一射頻電路230以及第二射頻電路240，並且用來判斷第一天線210以及第二天線220其中之一的訊號品質是否低於一臨界值來產生一判斷結果，並依據該判斷結果來決定是否切換第一射頻電路230以及第二射頻電路240其中之一的頻道以使得第一射頻電路230以及第二射頻電路240均操作在同一頻道(例如該第一頻道或該第二頻道)上。舉例來說，如果訊號處理單元250判斷第一天線210在該第一頻道上的訊號品質低於該臨界值，則訊號處理單元250就會將第二射頻電路240切換為操作在該第一頻道上。Please refer to FIG. 2, which is a simplified block diagram of an antenna diversity system 200 according to a first embodiment of the present invention, wherein the antenna diversity system 200 is a multiple input multiple output (Multi-Input). Multi-Output, MIMO) antenna system. As shown in FIG. 2 , the antenna diversity system 200 includes a first antenna 210 , a second antenna 220 , a first RF circuit 230 , a second RF circuit 240 , and a signal processing unit 250 . The first RF circuit 230 and the second RF circuit 240 are respectively coupled to the first antenna 210 and the second antenna 220, wherein the first RF circuit 230 and the second RF circuit 240 are respectively used to operate on a first channel. And a second channel, and the signal processing unit 250 is coupled to the first RF circuit 230 and the second RF circuit 240, and is used to determine whether the signal quality of one of the first antenna 210 and the second antenna 220 is A threshold value is generated to generate a determination result, and according to the determination result, whether to switch the channel of one of the first RF circuit 230 and the second RF circuit 240 such that the first RF circuit 230 and the second RF circuit 240 are both The operation is on the same channel (eg, the first channel or the second channel). For example, if the signal processing unit 250 determines that the signal quality of the first antenna 210 on the first channel is lower than the threshold, the signal processing unit 250 switches the second RF circuit 240 to operate at the first On the channel.
接著，在訊號處理單元250依據該判斷結果來切換第一射頻電路230以及第二射頻電路240其中之一的頻道以使得第一射頻電路230以及第二射頻電路240均操作在同一頻道上之後，訊號處理單元250還可以用來比較第一天線210與第二天線220之訊號品質；舉例來說，當第一射頻電路230以及第二射頻電路240均操作在該第一頻道上並且該第一頻道之傳輸容忍度比該第二頻道之傳輸容忍度低時(例如該第一頻道係為一影像傳輸頻道，以及該第二頻道係為一數據服務傳輸頻道)，如果訊號處理單元250判斷第一天線210在該第一頻道上的訊號品質低於第二天線220在該第一頻道上的訊號品質時，則訊號處理單元230就會將第一射頻電路240切換為操作在該第二頻道上。Then, after the signal processing unit 250 switches the channel of one of the first RF circuit 230 and the second RF circuit 240 according to the determination result, so that both the first RF circuit 230 and the second RF circuit 240 operate on the same channel, The signal processing unit 250 can also be used to compare the signal quality of the first antenna 210 and the second antenna 220; for example, when the first RF circuit 230 and the second RF circuit 240 are both operated on the first channel and the If the transmission tolerance of the first channel is lower than the transmission tolerance of the second channel (eg, the first channel is an image transmission channel, and the second channel is a data service transmission channel), if the signal processing unit 250 When the signal quality of the first antenna 210 on the first channel is lower than the signal quality of the second antenna 220 on the first channel, the signal processing unit 230 switches the first RF circuit 240 to operate. On the second channel.
如此一來，本發明之天線分集系統200可以先將兩個射頻電路230、240切換為操作在傳輸容忍度較低的一特定頻道上來讓訊號處理單元250量測與比較兩個不同天線210、220在該特定頻道上的訊號品質，然後再將在該特定頻道上具有較差訊號品質的一天線所對應的一射頻電路切換到傳輸容忍度較高的另一頻道，換句話說，訊號處理單元250可以選出在該特定頻道上具有較佳訊號品質的一天線來持續在該特定頻道上操作。因此，本發明之天線分集系統200可以針對傳輸容忍度較低的該特定頻道提供無中斷式的天線分集功能，讓傳輸容忍度較低的傳輸服務可以使用到最佳的天線來進行傳輸操作。In this way, the antenna diversity system 200 of the present invention can switch the two RF circuits 230, 240 to operate on a specific channel with low transmission tolerance, so that the signal processing unit 250 measures and compares two different antennas 210, 220 the signal quality on the particular channel, and then switching a radio frequency circuit corresponding to an antenna having poor signal quality on the particular channel to another channel with higher transmission tolerance, in other words, the signal processing unit 250 may select an antenna having a better signal quality on the particular channel to continue to operate on the particular channel. Therefore, the antenna diversity system 200 of the present invention can provide an uninterrupted antenna diversity function for the specific channel with low transmission tolerance, so that the transmission service with lower transmission tolerance can use the best antenna for the transmission operation.
舉例來說，在本發明之天線分集系統200中，假設一初始狀態係使用第一射頻電路230操作在5GHz頻帶的頻道上，亦即使用第一天線210在5GHz頻帶的頻道上傳輸對封包錯誤率(packet error rate)以及延遲性(latency)都較敏感並且傳輸容忍度較低的影像服務(video service)，而讓第二射頻電路240操作在2.4GHz頻帶的頻道上，亦即使用第二天線220在2.4GHz頻帶的頻道上傳輸傳輸容忍度較高的數據服務(data service)。For example, in the antenna diversity system 200 of the present invention, it is assumed that an initial state is operated on the channel of the 5 GHz band using the first RF circuit 230, that is, the first antenna 210 is used to transmit a packet on the channel of the 5 GHz band. The packet error rate and the latency are both sensitive and the video service is less tolerated, and the second RF circuit 240 is operated on the channel of the 2.4 GHz band. The two antennas 220 transmit a data service with a high transmission tolerance on a channel of the 2.4 GHz band.
當訊號處理單元250判斷第一天線210接收5GHz頻帶的頻道之影像訊號品質低於該臨界值時，訊號處理單元250便會把第二射頻電路240從2.4GHz頻帶的頻道切換到5GHz頻帶的頻道，也就是暫時中斷2.4GHz頻帶的頻道上之數據服務來將第二天線220與第一天線210同樣用來在5GHz頻帶的頻道上接收影像訊號，因此，5GHz頻帶的頻道上之影像服務不會中斷。接著，訊號處理單元250會比較第一天線210與第二天線220在5GHz頻帶的頻道上之訊號品質，如果訊號處理單元250判斷第一天線210在5GHz頻帶的頻道上之訊號品質比第二天線220在5GHz頻帶的頻道上之訊號品質好，則訊號處理單元250就會將第二射頻電路240從5GHz頻帶的頻道切換到2.4GHz頻帶的頻道，也就是訊號處理單元250會選擇繼續使用第一天線210在5GHz頻帶的頻道上接收影像訊號，以及使用第二天線220在2.4GHz頻帶的頻道上接收數據訊號；反之，如果訊號處理單元250判斷第一天線210在5GHz頻帶的頻道上之訊號品質比第二天線220在5GHz頻帶的頻道上之訊號品質差，則訊號處理單元250就會將第一射頻電路230從5GHz頻帶的頻道切換到2.4GHz頻帶的頻道，也就是訊號處理單元250會選擇繼續使用第二天線220在5GHz頻帶的頻道上接收影像訊號，以及使用第一天線210在2.4GHz頻帶的頻道上接收數據訊號。由於數據服務對於傳輸訊號的即時性要求較低，所以對於天線切換時造成的訊號中斷具有較高的傳輸容忍度，因此可利用通訊協定(protocol)來達成暫時性的中斷服務及恢復服務。此外，在此請注意，上述的實施例僅作為本發明的舉例說明，而不是本發明的限制條件。When the signal processing unit 250 determines that the image signal quality of the channel in which the first antenna 210 receives the 5 GHz band is lower than the threshold, the signal processing unit 250 switches the second RF circuit 240 from the channel of the 2.4 GHz band to the 5 GHz band. The channel, that is, the data service on the channel temporarily interrupting the 2.4 GHz band, uses the second antenna 220 and the first antenna 210 to receive the video signal on the channel of the 5 GHz band, and thus the image on the channel of the 5 GHz band. The service will not be interrupted. Then, the signal processing unit 250 compares the signal quality of the first antenna 210 and the second antenna 220 on the channel of the 5 GHz band, and if the signal processing unit 250 determines the signal quality ratio of the first antenna 210 on the channel of the 5 GHz band. When the signal quality of the second antenna 220 on the channel of the 5 GHz band is good, the signal processing unit 250 switches the second RF circuit 240 from the channel of the 5 GHz band to the channel of the 2.4 GHz band, that is, the signal processing unit 250 selects. Continue to use the first antenna 210 to receive the video signal on the channel of the 5 GHz band, and use the second antenna 220 to receive the data signal on the channel of the 2.4 GHz band; otherwise, if the signal processing unit 250 determines that the first antenna 210 is at 5 GHz If the signal quality on the channel of the frequency band is worse than the signal quality of the second antenna 220 on the channel of the 5 GHz band, the signal processing unit 250 switches the first RF circuit 230 from the channel of the 5 GHz band to the channel of the 2.4 GHz band. That is, the signal processing unit 250 will choose to continue to receive the video signal on the channel of the 5 GHz band using the second antenna 220, and use the first antenna 210 on the channel of the 2.4 GHz band. Received data signal. Since the data service has low requirements on the immediacy of the transmission signal, the signal interruption caused by the antenna switching has high transmission tolerance, so the protocol can be used to achieve temporary interruption service and recovery service. Moreover, it should be noted that the above-described embodiments are merely illustrative of the invention and are not limiting of the invention.

For example, if the signal processing unit 370 determines that the signal quality of the second antenna 320 and the third antenna 330 on the second channel is lower than the threshold, the signal processing unit 370 switches the first RF circuit 340. In order to operate on the second channel; if the signal processing unit 370 determines that the signal quality of the first antenna 310 on the first channel is lower than the threshold, the signal processing unit 370 will use the second RF circuit 350. And at least one of the third RF circuits 360 is switched to operate on the first channel.
接著，在訊號處理單元370依據該判斷結果來切換第一射頻電路340、第二射頻電路350以及第三射頻電路360至少其中之一的頻道以使得第一射頻電路340、第二射頻電路350以及第三射頻電路360中至少兩個射頻電路均操作在同一頻道上之後，訊號處理單元370還可以用來比較第一天線310、第二天線320以及第三天線330之訊號品質；舉例來說，當第一射頻電路340、第二射頻電路350以及第三射頻電路360均操作在該第一頻道上時，如果訊號處理單元370判斷第一天線310在該第一頻道上的訊號品質低於第二天線320以及第三天線330在該第一頻道上的訊號品質時，則訊號處理單元370就會將第一射頻電路340切換為操作在該第二頻道上；反之，如果訊號處理單元370判斷第一天線310在該第一頻道上的訊號品質高於第二天線320與第三天線330在該第一頻道上的訊號品質時，則訊號處理單元370就會將第二射頻電路350以及第三射頻電路360均切換為操作在該第二頻道上。Then, the signal processing unit 370 switches the channels of at least one of the first radio frequency circuit 340, the second radio frequency circuit 350, and the third radio frequency circuit 360 according to the determination result, so that the first radio frequency circuit 340, the second radio frequency circuit 350, and After the at least two radio frequency circuits of the third radio frequency circuit 360 are all operated on the same channel, the signal processing unit 370 can also be used to compare the signal quality of the first antenna 310, the second antenna 320, and the third antenna 330; for example, When the first RF circuit 340, the second RF circuit 350, and the third RF circuit 360 are both operated on the first channel, if the signal processing unit 370 determines the signal quality of the first antenna 310 on the first channel.
