为了更好地介绍本申请，首先介绍以下内容：
超奈奎斯特传输，即Faster-than-Nyquist Signaling，是目前被认为可以突破奈奎斯特采样速率，进一步逼近信道容量物理极限的一种新型信号处理技术。其衍生技术为X域重叠复用(Overlapped X Division Multiplexing,OVXDM)。OVXDM/FTN技术在时域/频域基于波形编码理论人为引入了ISI和/或信道干扰(Inter Channel Interference，ICI)，从而提高了码元发送速率，增加了等效信道容量。然而，波形编码后的信号对接收机的性能提出了更高的要求，增加了译码算法的复杂度以及硬件的功耗。一般来说，波形编码时的时频域重叠系数越大，即人为引入的ISI和ICI越严重，则接收机侧需要判断的状态数越多，接收算法的复杂度越高。
在城市里复杂的电磁波传输环境中，由于存在大量的散射、反射和折射面，造成了无线信号经不同路径到达接收天线的时刻不同，即传输的多径效应，不同路径信号造成的。当发送信号的前后符号经过不同路径同时抵达时，或者说，当后一个符号在前一个符号的时延扩展内到达时，即产生了ISI。类似的，在频域上，由于频偏效应，多普勒效应等原因，信号所在的各个子载波会产生频率上不同程度的偏移，造成原本可能正交的子载波产生重叠，即ICI。上述在信号传输过程中产生的ISI/ICI与发送时采用波形编码引入的ISI/ICI叠加，对接收机的译码能力产生了更高的要求。
目前学术界对衰落信道下的FTN/OVTDM***的研究成果表明，通过更加复杂的接收机算法对抗衰落信道。例如利用信道预均衡，联合信道译码的迭代算法等方法。但在实际应用中，一方面，实际***受成 本和功耗等条件限制，往往无法采用理想接收机，实现的译码算法复杂度有限，当ISI/ICI超出了一定阈值后，会无法正确译码。同时，接收机的译码复杂度增加时，也会增加能量消耗，不利于终端节能降耗。同时，大量仿真结果表明，FTN/OVTDM***相对传统OFDM***的吞吐量优势主要在于高信噪比(Signal Noise Ratio，SNR)区域。在高SNR区域，噪声对接收信号的影响程度相对较小，接收机易于根据已知的FTN/OVTDM的符号间编码的约束关系正确的进行译码，误码率很低。在低SNR区域，噪声对接收信号的影响程度相对较大，破坏了符号间编码的约束关系，使得误码率较高，不如传统的OFDM***。
基于上述原因，在实际***中，可以通过一些方式，例如利用无线信道的先验信息，利用信道测量结果等，尽量能量降低接收机算法的复杂度，以利于接收机能供跟踪衰落信道的时变特性，始终保持在最佳的工作状态。
一、FTN/OVTDM相关背景技术；
FTN/OVTDM是通过对发送信号进行移位叠加处理(又称波形编码)，人为地引入适量ISI和/或ICI一种信号处理方法，其目的是加快码元发送速率，即增加每赫兹每秒(Hz*s)内发送的符号数量。其中，FTN的全称为Faster-than-Nyquist，即超奈奎斯特。OVXDM包括OVTDM，OVFDM和OVCDM，以及OVTDM和OVFDM的组合技术，其全称为Overlapped X-Domain Multiplexing，即X域重叠复用。在下文中，统一用FTN指代。同时，引入的ISI和ICI会增加译码的复杂度，可能造成误码率的提升。然而，通过先进的译码算法可以抑制误码率提升带来的负面效应，综合来看仍然可以通过所述加快码元发送速率的方法提升信道容量。其表达式如下：
Figure PCTCN2022074970-appb-000001
其中，T Δ＝τT,τ∈(0,1),τ为时域重叠系数。特别的，在OVXDM中，取

因而有

Figure PCTCN2022074970-appb-000005
因而有
Figure PCTCN2022074970-appb-000006
图2是本申请实施例提供的无时域重叠与有时域重叠的信号对比示意图，下面以图2为例说明ISI的产生。当T＝0.8时，即时域波形重叠系数τ＝0.8后，经处理后的信号在在各个采样点所在时刻上，携带其他采样点信息的脉冲波形幅度不为零，因此产生了ISI，假设多径信道的冲激响应函数为h CH(t)，则经过信道后的信号可以等效地表示为：
Figure PCTCN2022074970-appb-000007
其中
Figure PCTCN2022074970-appb-000008
接收机收到的信号表达式为：
y(t)＝s′(t)+w(t)；                    (3)
其中w(t)为高斯白噪声。
FTN/OVTDM信号的生成主要有两种方式：1)在单天线***中，可以通过对信号过采样+成型滤波的方式来等效生成，其效果类似为一个作用于调制级别的卷积编码器；2)在多天线***中，可以采用更贴近其物理含义的方式来生成，即控制多天线的每个天线振子/端口按照既定的移位叠加原则，依次以T Δ的延迟来发送信号，不同天线振子/端口以不同延迟发送的信号在空口叠加，和信号的采样点之间引入了ISI，形成FTN/OVTDM信号。
由于波形编码和多径信道的叠加效应，导致了等效多径数量的增加，以及更加“靠近”的符号间隔和子载波间隔，使得等效的时频域重叠程度增加。这种时频域重叠程度的增加，在接收端反映为更加严重的ISI和ICI，对接收机的设计提出了挑战。理论性能最优的ML类型接收机的复杂度随着波形重叠程度上升而上升，当{K,N}较大时，硬件无法实现。而固定译码复杂度的快速算法对于较高重叠程度的信号无能为力。
本发明中，重叠系数为
Figure PCTCN2022074970-appb-000009
的FTN信号，等价为重叠层数为K的OVTDM信号。在后面的文本中，为表达简洁，可以统一用FTN指代FTN/OVTDM为代表的超奈奎斯特信号族。同时，可以采用重叠层数作为表示FTN/OVTDM信号特征的描述方式。
二、FTN信号的接收侧算法
图3是本申请实施例提供的FTN通信***收发端处理流程示意图，实际***中，FTN的收发处理流程如图3所示。其中红字标注的部分就是和基于奈奎斯特传输的通信***不同的地方。其中主要有两点区别：1)发射机中各个符号的间隔远远小于奈奎斯特传输的最小间隔，这样就造成了相邻数据之间的彼此重叠，即ISI；由此导致了2)，接收机必须采用白化滤波器和最大似然序列检测(Maximum likehood sequence estimation，MLSE)算法来消除这种ISI。
图4是本申请提供的接收机处理流程的示意图，与本发明有关的模块主要是白化滤波器模块。白化滤波器模块及其前后处理模块如图4所示。接收到的时域采样点y(t)经过匹配滤波和降采样后，输入到白化滤波器模块。此时，y(t)中原本由无线传输信道引起的加性白噪声经过匹配滤波后，变成了有色噪声，不利于后面的MLSE检测。因此，需要通过白化滤波模块，来把有色噪声还原成白噪声。抽象为数学模型的白化滤波器实际上是一个带状矩阵，其每一行非零元素就是对应的下一模块MLSE模块对应的抽头系数。对一个确定的***，白化滤波器对应的L矩阵可以通过如下方法计算。
首先，根据成型滤波器的系数g(t)＝[g 0g 1…g n]构造一个H矩阵。
Figure PCTCN2022074970-appb-000010
上述H矩阵中的L为所处理的数据时域采样点数，N为成型滤波器的时域采样点数。计算H的协方差矩阵R＝HH H，对所得的协方差矩阵R进行Cholesky分解。根据Cholesky定理有，R＝L HL。对求得的满足条件的L的共轭转置求逆得到L -H，即所需要的白化滤波器。
可以验证白化滤波可以恢复噪声的高斯分布特性。前述的公式(3)可以写成向量形式，如下：
Y＝S+N；                     (4)
在接收机侧经匹配滤波运算后得到：
Figure PCTCN2022074970-appb-000011
其中
Figure PCTCN2022074970-appb-000012
经匹配滤波后变成了有色噪声，需利用前述L进行白化处理：
Figure PCTCN2022074970-appb-000013
可以验证
Figure PCTCN2022074970-appb-000014
为高斯白噪声：
Figure PCTCN2022074970-appb-000015
求解白化滤波器的过程中，涉及到的矩阵求逆和Cholesky分解，在矩阵维度较大时，即L,N较大时，均难以在实际的硬件中实现。因此，需要找到一种方法避免接收机频繁求解白化滤波器的运算。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的信号处理方法进行详细地说明。
图5是本申请实施例提供的信号处理方法的流程示意图之一，如图5所示，该方法包括如下步骤：
步骤500，第一通信设备接收第二通信设备发送的第一指示信息，所述第一指示信息用于指示第二通信设备确定的白化滤波器的第一目标系数；
步骤510，第一通信设备基于所述白化滤波器的第一目标系数，处理接收到的第一信号。
可选地，第二通信设备为第一信号的发送侧，第一通信设备为第一信号的接收侧。
可选地，第一通信设备可以直接接收第二通信设备发送的第一指示信息，确定用于处理第一信号的白化滤波器的第一目标系数；然后可以基于所述白化滤波器的第一目标系数，处理接收到的第一信号。
可选地，通信***中，接收机算法涉及到的矩阵求逆和Cholesky分解运算复杂度较高，硬件设计难以实现，尤其在第一通信设备为终端时，对于对成本和功耗有更严苛要求的终端设备，影响了FTN技术的工程应用。
可选地，第二通信设备可以基于待传输的第一信号的时域采样点数，和传输第一信号所使用的第一成型滤波器的第二目标系数，计算获得白化滤波器的第一目标系数；并通过第一指示信息指示第一通信设备该计算获得的白化滤波器的第一目标系数，第一通信设备接收到第一指示信息后则可以获取白化滤波器的第一目标系数，即确定白化滤波器，用于处理接收到的所述第一信号。
可选地，基于前述公式(3)可以看出，噪声w(t)与信道冲激响应无关；因此白化滤波器的计算也无需考虑信道的冲激响应。因此，白化滤波器的计算只依赖于成型滤波器的系数，即第二目标系数，以及数据的帧结构；通信***中，以一个时隙为单位处理数据采样点，即一个时隙内发送的数据样点数量为H矩阵列的数量L，即第一信号的时域采样点数，而不需要随时变信道变化而变化。
