图3是GSM帧的一般结构以及GSM帧承载数据块的方式的示意图。 3 is a schematic embodiment of the general structure of the GSM frame and the GSM frame carry a data block. 持续时间为20毫秒(ms)的GSM帧被分为4个四分之一帧。 Duration of 20 milliseconds (ms) of the GSM frame is divided into four quarter-frame. 每一四分之一帧包括8个时隙(时隙0-7)。 Each quarter-frame comprises eight time slots (slots 0-7). 每个时隙大概持续625微秒(ys),包括左&、右边和中间码三部分。 Each slot lasts about 625 microseconds (YS), comprising three parts, a left & right, and the intermediate code. 时隙上左边和右边的射频脉冲承载数据,而中间码是训练序列。 RF pulse data carried on the left and right slots, the training sequence is a midamble.

根据所支持的调制编码方案模式,GSM帧的4个时隙上的射频脉冲,承〈 载一个分段的RLC (无线链路控制)块、 一个完全的RLC块或者两个RLC 块。 The modulation and coding scheme supported mode, the RF pulse on the time slots of the GSM frame, bearing <carrying a segmented RLC (radio link control) blocks, a block or two complete RLC RLC blocks. 例如,数据块A由四分之一帧1的时隙0、四分之一帧2的时隙0、四分之一帧3的时隙0和四分之一帧4的时隙0承载。 For example, data block A from the time slot 0 of quarter frame 1, slot 0 of quarter frame 2, slot 0 of quarter frame 3, and slot 4 of frame 0 one quarter of the carrier . 数据快A可以承载一个分段的RLC块、 一个RLC块或者两个RLC块。 Fast data A may carry a segmented RLC block, an RLC block, or two RLC blocks. 同样地,数据块B被四分之一帧1的时隙1、四分之一帧2的时隙1、四分之一帧3的时隙1和四分之一巾贞4的时隙1承载。 Likewise, data block B are quarter-frame 1 slot 1, frame 2 slot 1 quarter, quarter-frame 3 slot 1 and slot 4 of the quarter towel Zhen 1 carrier. 每一组时隙,即每个四分之一帧的时隙n的MCS模式,对于GSM帧来说,是一致的,但会随着GSM的变化而变化。 Each set of slots, i.e., slot n of each quarter frame of the MCS mode for GSM frame, is consistent, but will vary with changes in the GSM. 更进一步地,每一组时隙之间,其MCS模式是不相同的,如每一四分之一帧的时隙0的MCS模式, 与每一四分之一帧上时隙1-7的MCS模式,可能是不同的。 Furthermore, between each set of slots, which is not the same MCS mode, such as quarter-frame of each time slot 0 of the MCS mode, and quarter-frame time slots on each 1-7 the MCS mode may be different. 所述RLC块可以承载语音数据或其它数据。 The RLC block may carry voice data or other data.

图4描绘了把数据映射到射频脉冲中的各个步骤。 4 depicts the data is mapped to radio frequency pulses in respective steps. 数据最初是未编码的, 可能带有数据块报头。 Data is initially uncoded, possibly with a data block header. 块编码操作执行数据块的外部编码并支持对数据块进行检错/纠错。 Block coding operations perform the outer coding for the data block of the data block and support error detection / correction. 外部编码操作通常采用循环冗余码校验(CRC)或法尔码(Fire Code)。 Outer coding operations typically employ a cyclic redundancy check (CRC) or a Fire Code (Fire Code). 图中示出外部编码操作添加了数据的尾位和/或块编码序列(BCS),其附加在数据后。 It is shown the outer end of the encoding operation to add the data bits and / or block coding sequence (BCS), which is appended to the data. 在CS-1编码方案下,采用块编码和巻积编码对报头和数据一起编码,;在非CS-1编码方案下,报头和数据信息通常是分开编码的。 In CS-1 coding scheme using block coding and encoding convolving encoded header and data together; in the non-coding schemes CS-1, the header and data information is normally coded separately.

法尔码支持检错/纠错。 Fire code support for error detection / correction. 法尔码是把冗余位添加到数据报头位和数据位的截短二进制循环码。 Fire code is a redundant bit added to the data header and data bits of the truncated binary cyclic codes. 法尔码的纯检错能力强大到未被检测出来的错误得以通过的几率仅仅为2,。 Pure chance of error detection capability strong enough to Fire Code of undetected errors is by only 2 ,. 在块编码把用于检错的冗余位添加到数据中之后,计算用于纠错的附加冗余,以校正无线信道造成的传输差错。 After block coding adding redundant bits for error detection to the data, calculation of additional redundancy for error correction, to correct transmission errors caused by the radio channel. 内部的纠错或编码方案是基于巻积编码的。 Internal error correction or coding scheme is based on convolving encoding.

巻积编码器生成的一些冗余位可以在传送前进行凿孔(puncture)操作。 Convolving encoder generates some redundant bits can be punctured (puncturing so) before the transfer operation. 这种"凿孔"操作提高了巻积编码的速率,减少了每个传输的数据块的冗余。 This "punctured" convolving operation increases the rate coding, redundant data is reduced in each transmission block. "凿孔"还降低了对带宽的需求以使巻积编码信号适合可利用的信道比特流。 "Punctured" also reduces the bandwidth requirements such that the encoded signal for convolving the available channel bit stream. 巻积编码凿孔位被传给交错器,交错器把各种比特流交错后,分割成4个脉冲。 Convolving punctured coded bits are passed to an interleaver, the interleaver interleaving the streams of various bits, divided into four pulses. 图5是从射频脉冲中恢复数据块的相关步骤的示意框图。 FIG 5 is a schematic block diagram of the steps to restore the data block from the radio frequency pulse. 通常1个数据块由4个射频脉冲构成。 Typically a data block is composed of four RF pulse. 接收并处理这些脉冲。 These pulses are received and processed. 当4个射频脉冲都接收后, When the four RF pulses are received,

这4个射频脉冲被组合以形成一个编码数据块。 Four RF pulse are combined to form an encoded data block. 随后,该编码数据块被解凿孔(d印imcture)(如果需要的话),根据内部解码方案解码,接着根据外部编码方案解码。 Then, the punctured coded data block is decompressed (d printing imcture) (if required), the internal decoding scheme, and then decoded according to the outer coding scheme. 解码后的数据块包括数据块报头和数据。 The decoded data block includes a block header and data. 根据数据和报头被编码的方式,有可能进行部分解码就能识别数据。 The pattern data and header are coded, partial decoding is possible can be identified data.

图6是从传送的语音帧中恢复数据的才貝关步骤的示意框图。 6 is a schematic block diagram of a closed shell before the step of restoring data from the speech transmitted frame. 这个过程与图5的类似。 This process is similar to FIG. 5. 典型地,传送的是20毫秒的语音帧,其中,该语音帧的前半部分在第一串射频脉冲中传送,后半部分在第二串射频脉冲中传送。 Typically, the transfer is 20 msec speech frame, wherein the first half of the speech frame is transmitted in the first radio frequency pulse train, the second half of the second string transmitted RF pulse. 图6中所示的是一组4个射频脉冲,这4个脉冲与第一个语音帧一语音帧n的偏移量是10毫秒。 Shown in FIG. 6 is a set of four RF pulse, the offset for the first four pulses and a speech frame a speech frame n is 10 milliseconds. 其中,语音帧n的后半部分与后一个语音帧n+l的前半部分,被编码和交错到这4个射频脉冲中。 Wherein n in the second half of the speech frame with a speech frame after n + l is the first part, it is encoded and interleaved into four radio frequency pulses. 当这4个射频脉冲被处理后,编码块生成数据流,该数据流包含了语音帧n的的后半部分和语音帧n+l的的前半部分。 When four RF pulse is processed block to generate coded data stream, the data stream comprising the first half of the second half of the speech frame n and frame n + l speech is. 储存在存储器中的语音帧n的前半部分,可以与语音帧n的的后半部分结合, 生成有效的语音帧n相关的数据。 The first half of the speech frame n is stored in a memory, the n may be the second half of the speech frame combine to produce a valid voice frame n associated data.

图7所示的对语音帧n的数据的重编码,会产生至少部分重编码的数据脉冲,该重编码数据脉冲可以用于训练第二均衡器处理分支。 Re-encoded on the voice data of frame n shown in Figure 7, will produce at least partially re-encoded data pulses, the re-encoded data pulses may be used to train second equalizer processing branch. 如前所述,把从前一组射频脉冲恢复出来的语音帧前半部分,与从当前组射频脉冲恢复出来的语音帧后半部分进行组合,以生成语音帧的数据。 As described above, the recovered set of radio frequency pulses from the preceding first half of the speech frame, combined with the current set of radio frequency pulses from the recovered second half of the speech frames, speech frames to generate the data. 用循环冗余码校验对语音帧进行确认和纠错以生成有效语音帧。 And confirmed by cyclic redundancy check error correcting speech frames to produce a valid voice frame. 该有效语音帧随后被重编码。 The active speech frames are then re-encoded. 但是,只有重编码的语音帧n的后半部分用来部分再造射频脉冲。 However, only the n re-encoded speech frames to the second half portion of the RF pulse reconstruction. 可以对重编码的语音帧n的的后半部分进行分割和交错处理以生成部分编码的射频脉冲。 May be divided latter half of the re-encoded speech frames and interleaving the n RF pulses to generate a portion of coded. 因为语音帧n+l的后半部分还没有处理,所以这些射频脉冲仅是部分重编码的。 Because speech frame n + l yet processed the second half, these RF pulses are only partially re-encoded. 因为语音帧n+l没有被确认,所以重编码的语音帧n+l的前半部分不可能也未用于再造(recreate)射频脉冲。 Because speech frame n + l is not confirmed, the recoded speech frame n + l, the first half can not be not used for reconstruction (the recreate) RF pulse. 根据本发明的一个实施例,基于语音帧n的部分重编码的射频脉冲,结合已知的训练序列,能够更好地训练第二均衡器处理分支。 According to one embodiment of the present invention, based on the partial re-encoded speech frames n RF pulses, in conjunction with the known training sequence, to better train the second equalizer processing branch.

如图8A所示,处理流程自射频前端接收GSM帧相应的时隙上的射频脉冲开始(步骤802)。 As shown in the process flow in FIG. 8A GSM frame received from the RF front end of a respective RF pulse on the time slot (step 802). 然后,射频前端把射频脉冲转换成基带信号(步骤804)。 Then, converting the RF pulse RF front end to a baseband signal (step 804). 转换完成后,射频前端给基带处理器发送中断信号(步骤806)。 After the conversion, the RF front end sends an interrupt signal to the baseband processor (step 806). 这样,如图所示,射频前端执行步骤802-806。 Thus, as shown, the RF front end performs steps 802-806.

接着,基带处理器接收该基带信号(步骤808)。 Next, the baseband processor receiving the baseband signal (step 808). 在一个典型的操作中, 射频前端、基带处理器或调节器/解调器对该模拟基带信号采样以使基带信号数字化。 In a typical operation, the RF front end, the baseband processor or controller / demodulator sampling the analog baseband signal to digitize the signal baseband. 接收到基带信号(数字格式)后,基带处理器在步骤810中对基带信号的调制模式进行盲检测(blind detection)。 Upon receiving the baseband signal (in digital format), the baseband processor of the baseband signal modulation mode performs blind detection (blind detection) at step 810. 调制模式的盲检测确定了基带信号所对应的调制模式。 Blind detection of the modulation modes determined corresponding to the baseband signal modulation mode. 在一个优选的实施例里,根据GSM标准,调制模式既可以是高斯最小频移键控(GMSK)调制,也可以是8进制相移键控(8-PSK)调制。 In a preferred embodiment in accordance with the GSM standard, the modulation mode may be a Gaussian Minimum Shift Keying (GMSK) modulation, and may be 8-ary phase shift keying (8-PSK) modulation. 基带处理器确定调制模式后,基于所确定的调制模式,选择合适的处理分支进行处理(步骤812)。 The baseband processor determines the modulation mode based on the determined modulation mode, select the appropriate processing branch for processing (step 812).

对于GMSK调制,在步骤814中,基带处理器对基带信号进行反旋和步贞率校正。 For GMSK modulation, in step 814, the baseband processor of the baseband signal derotation step Zhen and correction. 接着,在步骤816中,基带处理器对基带信号进行脉冲功率评估。 Next, in step 816, the baseband processor of the baseband signal pulse power evaluation. 在步骤820中(见图8B分页连接箭头A),基带处理器接着进行定时(timing)、 信道、噪声、信噪比(SNR)评估。 In step 820 (see FIG. 8B tab connecting arrows A), then the baseband processor timing (Timing), channel noise ratio (SNR) evaluation. 随后,基带处理器执行自动增益控制(AGC) 循环计算(loop calculations)(步骤822)。 Subsequently, the baseband processor performs automatic gain control (AGC) loop calculation (loop calculations) (step 822). 接着,基带处理器对基带信号进行软决策比例因子的确定(步骤824)。 Next, the baseband processor of the baseband signal determined soft decision scaling factor (step 824). 步骤824之后,在步骤826中,基带处理器执行基带信号的匹配滤波操作。 After step 824, in step 826, the baseband processor performs matched filtering of the baseband signal operations.

步骤808-826称为预均衡处理操作。 Step called pre-equalization processing operations 808-826. 基带处理器对基带信号执行这些预均衡处理操作后,生成了处理后的基带信号。 After the baseband processor performing these pre-equalization processing operations on the baseband signal to generate the baseband signal processing. 完成这些预均衡处理之后,基带处理器给均衡器模块发送命令。 After completion of these pre-equalization processing, the baseband processor transmits a command to the equalizer module.

图10中更详细的描述了图9所示的多分支均衡器的第一处理分支。 FIG 10 is described in more detail in FIG multi-branch equalizer 9 shown in the first processing branch. 因为只有26个训练符号,第一处理分支可以训练具有4抽头(tap)的前馈滤波器908 和910,训练具有4抽头的反馈滤波器DFE。 Because only 26 training symbols, the training before the first processing branch may have 4 taps (TAP) 908 and a feedforward filter 910, a feedback filter DFE train having 4 taps.

以下的讨论将对间接训练法进行更详细的描述,该间接训练法是基于最小平方信道估测(LS-CE),与EDGE中所用的相似。 The following discussion will be indirect training method described in more detail, the indirect training method is based on the least square channel estimation (LS-CE), and similar to that used in EDGE. 首先用训练序列对信道进行估测,然后计算预滤波和MLSE参数同,如同它们是DFE的前馈或反馈滤波器。 First, a training sequence for channel estimation, and then calculate the parameters with the pre-filter and MLSE, as they are DFE feed-forward or feedback filter. 间接训练法的一个问题是CE (信道估测)较差,因为SAIC (单天线干扰消除)通常在低信号干扰比率(SIR)下运行。 One problem is the indirect training method CE (channel estimation) is poor, since SAIC (single antenna interference cancellation) is typically run at low signal to interference ratio (SIR). CE错误在计算滤波系数时扩大(propagates X Error CE expansion (propagates X in calculating the filter coefficients

图10中,MLSE输入端的信号模型可以认为是ISI信道加噪声。 10, MLSE input signal model may be considered as ISI channel plus noise. 假设DFE 反馈滤波器冲激响应是{b (0), b (1) ,... , b (Lb-1)}。 Suppose DFE feedback filter impulse response is {b (0), b (1), ..., b (Lb-1)}. 训练的目标就是对应于所给予的训练符号和所接收到的信号取得预滤波系数(f,(O),...t(Lf-l), f2 (0),….f2 (L厂l)}和MLSE参数b。 Training goal is given corresponding to a training symbol and the received signal to obtain pre-filter coefficients (f, (O), ... t (Lf-l), f2 (0), ... .f2 (L l Factory )}, and the MLSE parameters b.

基于以上模式,MLSE输入端的噪声是: Based on the above model, MLSE input noise:

式表示为: n二Xf-Sb Expressed as follows: n two Xf-Sb

均衡器的判别式就是找到f和b,以使MLSE的输入噪声最小, 即min II n || 2。 Discriminant equalizer is to find f and B, so that the MLSE input noise minimal, i.e. min II n || 2.

因为训练符号的数目是有限的,所以f和b的联合优化对噪声是敏感的。 Because the number of training symbols is limited, joint optimization of f and b is sensitive to noise.

20下面讨论用次优的方案仅将估测的参数减少到预滤波f 。 The only decrease with suboptimal solutions to the parameter estimation are discussed below f 20 pre-filtering.

预滤波输出(Xf)与训练符号之间的交互作用可以用MLSE输入(b)端的工SI信道表示。 Interaction between the pre-filter outputs (Xf) and training symbol may be represented by the MLSE input (b) end of work SI channel. 因此,b可以用f表示。 Thus, b can be represented by f. 在预滤波的输出使用LS CE, b作为信道估测- Use LS CE at the pre-filtered output, b as channel estimation -

b = S+X f b = S + X f

其中,0+表示伪逆(psecdo-inverse)。 Wherein 0 + denotes the pseudo inverse (psecdo-inverse). 取代上式将取得函数的最小值,得到: The substituents on the acquired minimum function formula to obtain:

min II Xf-SS+Xf || 2=min || (I-SS+)Xf || 2=minf, Af min II Xf-SS + Xf || 2 = min || (I-SS +) Xf || 2 = minf, Af

其中,A = X' (I-SS+)X,(),是转置操作。 Wherein, A = X '(I-SS +) X, (), it is a transpose operation. 为了避免平凡解,应用了约束条件。 To avoid the trivial solution, the application of the constraints. 常用的两种约束是最小整数范式(Unit-norm)约束和线性约束。 Two common constraint is the smallest integer paradigm (Unit-norm) linear constraints and constraints. 当采用了范式1约束时,最优解是对应于最小的本征值的的本征向量A: When a paradigm constraints, optimal solution corresponding to the smallest eigenvalue of the eigenvector A:

f=eigvec(A) f = eigvec (A)

可以给f选择线性约束。 Linear constraints to be selected f. 例如,我们可以把b的第i个元固定为l。 For example, we can put the i-th element of b is fixed to l. 换句话说,MLSE信道b的第i个抽头是1。 In other words, MLSE channel b of the i-th taps 1. 当c是(S+X)的第i个行向量时,线性约束为: When c is (S + X) is the i-th row vector of linear constraints:

cf=l cf = l

对应的最优解是: Corresponding optimal solution is:

f=AV f = AV

通常线性约束优于最小整数范式约束。 Linearly Constrained generally better than the smallest integer constraint paradigm. 在线性约束中,如果把第一抽头选为l,上式的最小判别式等于DFE判别式。 Linear constraint, if the first tap preferably L, the smallest discriminant formula discriminant equal to DFE. 对角加载法(diagonal loading)也有助于高SIR范围。 Diagonal loading method (diagonal loading) also contributes to a high SIR range.

图11更详细地描述了图9所示的多分支均衡器的第二处理分支。 FIG 11 is described in more detail with the multi-branch equalizer shown in FIG. 9, a second processing branch. 信道解码之后,数据被重编码和用于训练7抽头LE 924和926。 After channel decoding, the data is re-encoded and used to train 7 tap LE 924 and 926. 给第二处理分支选择LE是因为帧间交错(inter-frame interleaving)。 Selecting a second processing branch LE because inter-frame interleaving (inter-frame interleaving). 与语音帧相关的重编码位可以只提供半个脉冲(即使是数据位)。 Associated with the re-encoded bit speech frame may only provide half of the pulse (even data bits). DFEs需要给反馈滤波器提供连贯的取样。 DFEs need to provide coherent sampling to the feedback filter. 另外,LE比DFE(MLSE)简单。 Further, LE ratio DFE (MLSE) simple. 采用完全重编码位的其它实施例则可以给第二处理分支采用DFE而不采用LE。 Other embodiments employ fully re-encoded bits to a second processing branch may be employed without using a DFE LE.

步骤1220中,用第二处理分支从存储器中恢复射频脉冲。 In step 1220, a second processing branch recovery RF pulse from the memory. 这可以包括恢复一个或多个经第二均衡器处理分支处理的脉冲。 This recovery may include one or more processing pulses through the second branch equalizer processing. 步骤1222中,这些重编码的数据位被作为信号提供以训练第二均衡器处理分支。 In step 1222, the re-encoded data bits are provided to train the second equalizer processing branch as a signal. 步骤1224中,用第二均衡器处理分支均衡存储在存储器中的射频脉冲,其中,第二均衡器处理分支不仅被己知的训练序列训练,也被至少一些由信道解码器的原始输出生成的部分重编码的数据位训练。 In step 1224, a second equalizer processing branch equalized RF pulse stored in the memory, wherein the second equalizer processing branch is trained not only the known training sequence, also at least some of the original output of the channel generated by the decoder portion of the training data bits are re-encoded. 不仅使用已知的训练序列,还使用重编码的数据位,是为了更好地训练第二均衡器处理分支和更好地均衡,从而使第二均衡器处理分支提供比第一均衡器处理分支更优良的输出。 Using not only the known training sequence, but also using the re-encoded data bits in order to better train the second equalizer processing branch and better balanced, so that the second equalizer processing branch to provide a first equalizer processing branch ratio better output. 第二均衡器处理分支生成替换的软决策,在步骤1226中,这些软决策被解交错;在步骤1228中,这些软决策被解码以在步骤1230中生成替换数据帧。 Second equalizer processing branch soft decisions generated Alternatively, in step 1226, the soft decisions are deinterleaved; In step 1228, the soft decisions are decoded in step 1230 to generate replacement data frame.

在噪声限制方案中,对单天线的干扰消除比传统的接收器差。 In noise-limited embodiment, a single antenna interference cancellation worse than a conventional receiver. 另外,由于预滤波长度短,长延迟的信道(如山区的地形)还将使性能大幅下降。 Further, due to the short pre-filter length, a long delay of the channel (e.g., mountainous terrain) performance also dropped significantly. 为解决这个问题,添加了一个交换功能以便进行交互式单天线干扰处理。 To solve this problem, it adds a switching function for interactive processing of single antenna interference. 该交换功能可以基于SNR、有色噪声识别器和信道属性探测器的任意组合。 This switching function may be based on SNR, any combination of colored noise and channel identifier attribute detector.
