Description

信号处理方法及装置
本申请要求于2018年11月30日提交的申请号为201811460030.5、发明名称为“信号处理方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，特别涉及一种信号处理方法及装置。
背景技术
通信设备工作在不同的系统配置下时会设置不同的通道数和载波数，通道数和载波数的设置分别涉及通信设备中射频模块和基带模块的处理。射频模块中的通道在硬件上往往是固定的设计，即射频模块中的通道的数量往往是一定的。而受限于基带模块的处理能力，基带模块能够处理的通道数与载波数是互斥的，如基带模块在配置成两通道处理能力时，最多只能处理40兆赫的载波，在配置成四通道处理能力时，最多只能处理30兆赫的载波。因此，为了满足不同的系统配置要求，往往需要对射频模块中的通道输出的信号进行合并后再传输给基带模块，以使得射频模块输入至基带模块的信号的数量小于或等于基带模块能够处理的通道数，便于基带模块对所输入的信号的正常处理。
相关技术中，是通过合路分路开关来对射频模块中的通道输出的信号进行合并。具体地，如图1所示，假设射频模块中有4个通道，这4个通道的输出端分别为A1、A2、B1和B2，基带模块的输入端分别为C1、C2、D1和D2，A1和A2一一与第一合路分路开关的两个第一端连接，C1和C2一一与第一合路分路开关的两个第二端连接，B1和B2一一与第二合路分路开关的两个第一端连接，D1和D2一一与第二合路分路开关的两个第二端连接。通过控制第一合路分路开关可以使A1和A2处于分路状态或合路状态，通过控制第二合路分路开关可以使B1和B2处于分路状态或合路状态。分路状态时，A1、A2、B1和B2一一直通C1、C2、D1和D2，如此可以将射频模块中的这4个通道输出的4个信号直接传输给基带模块；合路状态时，C1对应A1和A2的合路，C2悬空，D1对应B1和B2的合路，D2悬空，如此可以将射频模块中的这4个通道输出的4个信号合并为2个信号后再传输给基带模块。
然而，上述方式中需要增加第一合路分路开关和第二合路分路开关这两个硬件开关，才能实现对射频模块中的通道输出的信号的合并，因而不仅会增加硬件成本，且会带来硬件复杂度的提升。另外，在射频模块与基带模块之间设置第一合路分路开关和第二合路分路开关，会带来一定的信号损耗(即第一合路分路开关和第二合路分路开关的插损)。
发明内容
本申请提供了一种信号处理方法及装置，可以解决相关技术中信号合并时硬件成本较高且信号损耗较高的问题。所述技术方案如下：

其中，所述根据所述目标合路策略和所述目标合路策略的m组合路系数，对所述基带模块输出的m个信号进行分路处理，得到与所述n个通道一一对应的n个第二信号，包括：根据目标合路策略确定目标分路策略，所述目标分路策略用于指示将所述基带模块输出的m个信号分离为n个信号；将所述目标合路策略的m组合路系数确定所述目标分路策略的m组分路系数；按照所述目标分路策略和所述目标分路策略的m组分路系数，对所述基带模块输出的m个信号进行分路处理，得到与所述n个通道一一对应的n个第二信号。
在本申请实施例中，目标分路策略用于指示将该n个通道转换为m组通道，基带模块输出的m个信号与该m组通道一一对应，且目标分路策略指示将该m个信号中的每个信号分离到对应的一组通道中所有的通道上，如此即可将该m个信号分离为n个信号。目标分路策略的m组分路系数与目标分路策略指示转换为的m组通道一一对应，对于该m组分路系数中的每组分路系数，这组分路系数所有的分路系数与对应的一组通道中所有的通道一一对应，对于这组分路系数中的每个分路系数，这个分路系数是在将这组分路系数对应的一个信号分离到这个分路系数对应的一个通道上时使用。
其中，所述根据所述n个通道对应的信道状态信息，确定多个合路策略中每个合路策略的m组合路系数，包括：根据预设干扰抑制算法和所述n个通道对应的信道状态信息，确定所述n个通道中的每个通道对应的干扰抑制系数；根据预设合并算法和所述n个通道对应的信道状态信息，确定所述多个合路策略中每个合路策略对应的m组合并系数，所述m组合并系数与所述m组通道一一对应，且每组合并系数中所有的合并系数与对应的一组通道中所有的通道一一对应；根据所述n个通道中每个通道对应的干扰抑制系数和所述多个合路策略中每个合路策略对应的m组合并系数，确定所述多个合路策略中每个合路策略的m组合路系数。
在本申请实施例中，可以根据预设干扰抑制算法确定出干扰抑制系数，以及根据预设合并算法确定出合并系数，继而根据确定出的干扰抑制系数和合并系数，来确定合路策略的m组合路系数，从而大大提高了确定出的合路系数的准确度。
其中，所述根据所述n个通道对应的信道状态信息和所述多个合路策略中每个合路策略的m组合路系数，从所述多个合路策略中确定目标合路策略，包括：根据所述n个通道对应的信道状态信息和所述多个合路策略中每个合路策略的m组合路系数，确定所述多个合路策略中每个合路策略对应的性能指标值，所述性能指标值为信噪比或信干比；将所述多个合路策略中性能指标值最大的合路策略确定为目标合路策略。
在本申请实施例中，性能指标值用于指示对信号进行合路处理后得到的信号的性能好坏，因而将该多个合路策略中性能指标值最大的合路策略确定为目标合路策略后，后续使用目标合路策略来对信号进行合路处理时，可以保证合路处理后得到的信号的性能较好。

步骤401：在采集周期内，获取射频模块中的n个通道中每个通道对应的信道状态信息，n为大于或等于2的整数。
值得注意的是，步骤401的操作可以由基带模块来执行，具体可以由基带模块中的第二接口来执行，第二接口用于接收射频模块输出的信号。基带模块能够处理的通道数可以小于 n。
需要说明的是，采集周期是用于确定进行合路处理时所要使用的目标合路策略的周期。实际应用中，可以每隔一段时间就启动一个采集周期，也可以每当检测到信道波动(如功率波动等)或系统变化(如硬件变化等)时就启动一个采集周期，且可以在确定出进行合路处理时所要使用的目标合路策略时结束这个采集周期，当然，也可以在其它情况下启动或结束采集周期，本申请实施例对此不作限定。
另外，该n个通道中的每个通道均用于将天线接收到的信号输出到基带模块，此时该n个通道中的每个通道均可以输出一个信号，该n个通道总共可以输出n个信号。天线可以具有n个天线端口，天线接收到信号后，可以将接收到的信号通过该n个天线端口一一传输到该n个通道，该n个通道中的每个通道可以将天线输入的信号传输到基带模块。
再者，信道状态信息为通信链路的信道属性，可以描述信号在每条传输路径上的衰弱因子，该信道状态信息可以包括信号幅度、信号相位、信号功率、噪声功率等。
具体地，获取射频模块中的n个通道中每个通道对应的信道状态信息时，可以先获取该n个通道中每个通道输出的信号，再根据每个通道输出的信号，通过信道估计算法获取每个通道对应的信道状态信息。当然，也可以通过其它方式获取射频模块中的n个通道中每个通道对应的信道状态信息，本申请实施例对此不作限定。
其中，获取该n个通道中每个通道输出的信号时，如果第二接口的传输带宽不受限，即如果第二接口最多能够同时传输的信号的数量等于n，则可以直接获取该n个通道中每个通道输出的信号；如果第二接口的传输带宽受限，即如果第二接口最多能够同时传输的信号的数量为a，且a为小于n的正整数，则可以分时获取该n个通道中每个通道输出的信号，具体可以将该n个通道划分为b组，该b组通道中的每组通道的通道数量均为a，之后，在一段时间内获取该b组通道中的第1组通道中所有的通道输出的信号，再在下一段时间内获取该b组通道中的第2组通道中所有的通道输出的信号，以此类推，直至在某一段时间内获取该b组通道中的第b组通道中所有的通道输出的信号为止，如此可以获取到该n个通道中每个通道输出的信号。
其中，根据每个通道输出的信号，通过信道估计算法获取每个通道对应的信道状态信息的操作可以参考相关技术，本申请实施例对此不进行详细阐述。该信道估计算法可以为基于训练序列的估计算法、基于导频的估计算法、盲估计算法等，本申请实施例对此不作限定。
步骤402：在采集周期内，根据该n个通道对应的信道状态信息，确定多个合路策略中每个合路策略的m组合路系数。
值得注意的是，步骤402的操作可以由基带模块来执行，具体可以由基带模块中的第二接口来执行。
需要说明的是，多个合路策略可以预先进行设置，该多个合路策略中的每个合路策略用于指示将该n个通道转换为m组通道，且指示将每组通道中所有的通道输出的信号合并为一个信号。如此，该多个合路策略中的每个合路策略是指示将该n个通道输出的n个信号合并为m个信号。
例如，该n个通道包括通道1、通道2、通道3和通道4，该多个合路策略包括合路策略1和合路策略2，m为2。合路策略1可以指示将通道1和通道2转换到一组，将通道3和通道4转换到一组，且指示将通道1输出的信号和通道2输出的信号合并为一个信号，将通道 3输出的信号和通道4输出的信号合并为一个信号，如此，合路策略1是指示将这4个通道输出的4个信号合并为2个信号。合路策略2可以指示将通道1、通道2和通道3转换到一组，将通道2和通道4转换到一组，且指示将通道1输出的信号、通道2输出的信号和通道3输出的信号合并为一个信号，将通道2输出的信号和通道4输出的信号合并为一个信号，如此，合路策略2是指示将这4个通道输出的4个信号合并为2个信号。
另外，m为小于n的正整数，且m小于或等于基带模块能够处理的通道数。m可以根据基带模块的通道处理能力来进行设置，例如，当基带模块具有四通道处理能力时，即当基带模块能够处理的通道数为4时，可以将m设置为大于或等于1且小于或等于4的任一整数。这种情况下，根据该多个合路策略中的任一合路策略将该n个通道输出的n个信号合并为m个信号后，基带模块能够对该m个信号进行正常处理。
再者，每个合路策略的m组合路系数与这个合路策略指示转换为的m组通道一一对应，且每组合路系数中所有的合路系数与对应的一组通道中所有的通道一一对应，此时每组合路系数中的每个合路系数用于在对这一组通道中对应的一个通道输出的信号进行合路处理时使用。
具体地，根据该n个通道对应的信道状态信息，确定多个合路策略中每个合路策略的m组合路系数的操作可以通过如下两种方式实现：
第一种方式：根据预设合并算法和该n个通道对应的信道状态信息，确定该多个合路策略中每个合路策略对应的m组合并系数；将每个合路策略对应的m组合并系数确定为这个合路策略的m组合路系数。
需要说明的是，预设合并算法可以预先进行设置，如预设合并算法可以为最大比合并算法、等增益合并算法、选择合并算法等，本申请实施例对此不作限定。
另外，每个合路策略对应的m组合并系数与这个合路策略指示转换为的m组通道一一对应，且每组合并系数中所有的合并系数与对应的一组通道中所有的通道一一对应。
其中，根据预设合并算法和该n个通道对应的信道状态信息，确定该多个合路策略中每个合路策略对应的m组合并系数时，对于该多个合路策略中的每个合路策略，可以确定这个合路策略指示转换为的m组通道；对于该m组通道中的每组通道，根据预设合并算法和这组通道中所有的通道中每个通道对应的信道状态信息，获取这组通道中所有的通道中每个通道对应的合并系数，以得到这组通道对应的一组合并系数；将与该m组通道一一对应的m组合并系数确定为这个合路策略对应的m组合并系数。
需要说明的是，根据预设合并算法和这组通道中所有的通道中每个通道对应的信道状态信息，获取这组通道中所有的通道中每个通道对应的合并系数的操作可以参考相关技术，本申请实施例对此不进行详细阐述。
第二种方式：根据预设干扰抑制算法和该n个通道对应的信道状态信息，确定该n个通道中的每个通道对应的干扰抑制系数；根据预设合并算法和该n个通道对应的信道状态信息，确定该多个合路策略中每个合路策略对应的m组合并系数；根据该n个通道中每个通道对应的干扰抑制系数和该多个合路策略中每个合路策略对应的m组合并系数，确定该多个合路策略中每个合路策略的m组合路系数。
需要说明的是，预设干扰抑制算法可以预先进行设置，如预设干扰抑制算法可以为迫零(Zero Foring，ZF)算法、最小均方误差(Minimum Mean Squared Error，MMSE)算法等， 本申请实施例对此不作限定。
另外，根据预设干扰抑制算法和该n个通道对应的信道状态信息，确定该n个通道中的每个通道对应的干扰抑制系数的操作可以参考相关技术，本申请实施例对此不进行详细阐述。
再者，根据预设合并算法和该n个通道对应的信道状态信息，确定该多个合路策略中每个合路策略对应的m组合并系数的操作与上述第一种方式中根据预设合并算法和该n个通道对应的信道状态信息，确定该多个合路策略中每个合路策略对应的m组合并系数的操作相同，本申请实施例对此不再赘述。
其中，根据该n个通道中每个通道对应的干扰抑制系数和该多个合路策略中每个合路策略对应的m组合并系数，确定该多个合路策略中每个合路策略的m组合路系数时，对于该多个合路策略中每个合路策略，可以确定这个合路策略指示转换为的m组通道；对于这个合路策略对应的m组合并系数中的每组合并系数，确定这组合并系数在该m组通道中对应的一组通道；确定这组合并系数中的每个合并系数在这组通道中对应的一个通道；将这个合并系数与这个通道对应的干扰抑制系数相乘，得到这个通道对应的合路系数，如此可以得到这组通道中每个通道对应的合路系数，即得到这组通道对应的一组合路系数；将与该m组通道一一对应的m组合路系数确定为这个合路策略的m组合路系数。
步骤403：在采集周期内，根据该n个通道对应的信道状态信息和该多个合路策略中每个合路策略的m组合路系数，从该多个合路策略中确定目标合路策略。
值得注意的是，步骤403的操作可以由基带模块来执行，具体可以由基带模块中的第二接口来执行。
需要说明的是，目标合路策略为该多个合路策略中合路性能最佳的合路策略，目标合路策略可以在后续对该n个通道输出的n个信号进行合路处理时使用。
具体地，根据该n个通道对应的信道状态信息和该多个合路策略中每个合路策略的m组合路系数，从该多个合路策略中确定目标合路策略时，可以根据该n个通道对应的信道状态信息和该多个合路策略中每个合路策略的m组合路系数，确定该多个合路策略中每个合路策略对应的性能指标值；将该多个合路策略中性能指标值最大的合路策略确定为目标合路策略。当然，也可以根据该n个通道对应的信道状态信息和该多个合路策略中每个合路策略的m组合路系数，通过其它方式从该多个合路策略中确定目标合路策略，本申请实施例对此不作限定。
需要说明的是，性能指标值用于指示对信号进行合路处理后得到的信号的性能好坏，该性能指标值可以为信噪比、信干比等，本申请实施例对此不作限定。某个合路策略对应的性能指标值越大，按照这个合路策略对信号进行合路处理后得到的信号的性能越好。
其中，根据该n个通道对应的信道状态信息和该多个合路策略中每个合路策略的m组合路系数，确定该多个合路策略中每个合路策略对应的性能指标值时，可以对于该多个合路策略中的每个合路策略，确定这个合路策略指示转换为的m组通道；对于该m组通道中的每组通道，根据这组通道中所有的通道对应的信道状态信息，确定将这组通道中所有的通道输出的信号合并后得到的一个信号的性能指标值，并将这个信号的性能指标值确定为这组通道对应的性能指标值；将该m组通道对应的性能指标值的平均值确定为这个合路策略对应的性能指标值。
需要说明的是，根据这组通道中所有的通道对应的信道状态信息，确定将这组通道中所 有的通道输出的信号合并后得到的一个信号的性能指标值的操作可以参考相关技术，本申请实施例对此不进行详细阐述。
值得注意的是，在采集周期内通过上述步骤401-步骤403确定目标合路策略后，后续即可使用目标合路策略对该n个通道输出的n个信号进行合路处理来得到m个信号，如此可以从n路信号切换到m路信号，基带模块随后就可以正常进行m路信号的接收处理。具体地，该合路处理的过程可以包括如下步骤404-步骤405。
步骤404：在第一处理周期内，按照目标合路策略和目标合路策略的m组合路系数，对该n个通道输出的n个信号进行合路处理，得到m个第一信号。
值得注意的是，步骤404的操作可以由基带模块或射频模块来执行，具体可以由基带模块中的第二接口或射频模块中的第一接口来执行，第一接口用于将该n个通道输出的信号传输给基带模块。
需要说明的是，第一处理周期是进行合路处理的周期，第一处理周期是与采集周期不同的周期。实际应用中，可以每在采集周期结束时就启动一个第一处理周期，每在采集周期开始时就结束这个第一处理周期，当然，也可以在其它情况下启动或结束第一处理周期，本申请实施例对此不作限定。
具体地，按照目标合路策略和目标合路策略的m组合路系数，对该n个通道输出的n个信号进行合路处理，得到m个第一信号时，可以按照目标合路策略，将该n个通道转换为m组通道；对于该m组通道中的每组通道，确定目标合路策略的m组合路系数中与这组通道对应的一组合路系数；将这组合路系数中的每个合路系数作为这组通道中与这个合路系数对应的一个通道输出的信号的权重后，对这组通道输出的信号进行加权处理，得到这组通道对应的一个合并信号；将与该m组通道一一对应的m个合并信号确定为m个第一信号。
步骤405：通过基带模块对该m个第一信号进行处理。
由于基带模块能够处理的通道数大于或等于m，所以基带模块能够对m个第一信号进行正常处理。本申请实施例中先将射频模块中的n个通道输出的n个信号合并为了m个第一信号，再由基带模块处理该m个第一信号，如此，提供了一种灵活的通道配置方案，在不增加额外的硬件成本，不带来额外的损耗(如合路分路开关的插损)的情况下，将n路信号切换为了m路信号，在充分利用射频模块的接收资源的基础上，可以满足基带模块的通道处理要求。
为了便于理解，下面结合图5来对上述步骤401-步骤405的操作进行举例说明。
参见图5，在采集周期内，基带模块中的第二接口先获取射频模块中的n个通道中每个通道对应的信道状态信息，再根据该n个通道对应的信道状态信息，确定多个合路策略中每个合路策略的m组合路系数，然后根据该n个通道对应的信道状态信息和该多个合路策略中每个合路策略的m组合路系数，从该多个合路策略中确定目标合路策略。进一步地，第二接口还可以将目标合路策略和目标合路策略的m组合路系数传输到射频模块中的第一接口。
在第一处理周期内，基带模块中的第二接口或者射频模块中的第一接口按照目标合路策略和目标合路策略的m组合路系数，在第一处理周期内对该n个通道输出的n个信号进行合路处理，得到m个第一信号，然后将该m个第一信号传输到基带模块，由基带模块对该m个第一信号进行处理。
值得注意的是，在采集周期内通过上述步骤401-步骤403确定目标合路策略后，不仅可 以使用目标合路策略来对信号进行合路处理，还可以当该n个通道中的每个通道还用于将基带模块输出的信号通过天线进行发射时，使用目标合路策略来对信号进行分路处理。具体地，该分路处理的过程可以包括如下步骤406-步骤407。
步骤406：在第二处理周期内，根据目标合路策略和目标合路策略的m组合路系数，对基带模块输出的m个信号进行分路处理，得到与该n个通道一一对应的n个第二信号。
值得注意的是，步骤406的操作可以由基带模块或射频模块来执行，具体可以由基带模块中的第三接口或射频模块中的第四接口来执行，第三接口用于将基带模块输出的信号传输到射频模块，第四接口用于接收基带模块输出的信号。
需要说明的是，第二处理周期是进行分路处理的周期，第二处理周期是与采集周期不同的周期。第二处理周期可以与第一处理周期是相同的周期，也可以与第二处理周期是不同的周期，本申请实施例对此不作限定。实际应用中，可以每在采集周期结束时就启动一个第二处理周期，每在采集周期开始时就结束这个第二处理周期，当然，也可以在其它情况下启动或结束第二处理周期，本申请实施例对此不作限定。
另外，基带模块可以将生成的信号输出到射频模块，射频模块可以将接收到的信号通过该n个通道传输到天线，天线可以将接收到的信号发射出去。
具体地，根据目标合路策略和目标合路策略的m组合路系数，对基带模块输出的m个信号进行分路处理，得到与该n个通道一一对应的n个第二信号时，可以根据目标合路策略确定目标分路策略；将目标合路策略的m组合路系数确定为目标分路策略的m组分路系数；按照目标分路策略和目标分路策略的m组分路系数，对基带模块输出的m个信号进行分路处理，得到与该n个通道一一对应的n个第二信号。
需要说明的是，目标分路策略用于指示将基带模块输出的m个信号分离为n个信号。具体地，目标分路策略用于指示将该n个通道转换为m组通道，基带模块输出的m个信号与该m组通道一一对应，且目标分路策略指示将该m个信号中的每个信号分离到对应的一组通道中所有的通道上，如此即可将该m个信号分离为n个信号。
另外，该m组分路系数与目标分路策略指示转换为的m组通道一一对应，对于该m组分路系数中的每组分路系数，这组分路系数所有的分路系数与对应的一组通道中所有的通道一一对应，对于这组分路系数中的每个分路系数，这个分路系数是在将这组分路系数对应的一个信号分离到这个分路系数对应的一个通道上时使用。
其中，根据目标合路策略确定目标分路策略时，可以直接将目标合路策略指示转换为的m组通道确定为目标分路策略指示转换为的m组通道，以得到目标分路策略。
其中，按照目标分路策略和目标分路策略的m组分路系数，对基带模块输出的m个信号进行分路处理，得到与该n个通道一一对应的n个第二信号时，可以按照目标分路策略，将该n个通道转换为m组通道；对于该m组通道中的每组通道，确定目标分路策略的m组分路系数中与这组通道对应的一组分路系数，且确定基带模块输出的m个信号中与这组通道对应的一个信号，对于这组通道中的每个通道，确定这组分路系数中与这个通道对应的一个分路系数，将基带模块输出的这个信号与这个分路系数相乘，得到这个通道对应的一个分离信号；对于该n个通道中的每个通道，将这个通道对应的所有分离信号相加，得到这个通道对应的第二信号。
步骤407：在第二处理周期内，将该n个第二信号中的每个第二信号通过该n个通道中 对应的通道进行发射。
本申请实施例中先将基带模块输出的m个信号分离为n个第二信号，再将该n个第二信号一一通过该n个通道进行发射，如此，提供了一种灵活的通道配置方案，在不增加额外的硬件成本，不带来额外的损耗(如合路分路开关的插损)的情况下，将m路信号切换为了n路信号，在满足基带模块的通道处理要求的基础上，可以充分利用射频模块的发射资源。
值得注意的是，本申请实施例中，可以每隔一段时间就启动一个采集周期，也可以每当检测到信道波动或系统变化时就启动一个采集周期。当在这个采集周期内确定出目标合路策略和目标合路策略的m组合路系数后，就可以在这个采集周期之后的第一处理周期内使用目标合路策略和目标合路策略的m组合路系数来进行合路处理，且可以在这个采集周期之后的第二处理周期内使用目标合路策略和目标合路策略的m组合路系数来进行分路处理。如此，实现了对所使用的合路策略及其合路系数的定期刷新，保证了所使用的合路策略及其合路系数的准确性，继而保证了合路处理和分路处理时的准确性。
另外，在接收信号的情况下，在尚未确定出目标合路策略和目标合路策略的m组合路系数时，可以从该多个合路策略中选择一个合路策略作为默认的合路策略，并依据经验或这个默认的合路策略的历史合路系数来为这个默认的合路策略设置m组合路系数，然后，使用这个默认的合路策略及其m组合路系数来进行合路处理。或者，如果第一接口和第二接口的传输带宽不受限，即如果第一接口和第二接口最多能够同时传输的信号的数量等于n，则射频模块可以直接将该n个通道输出的n个信号传输到基带模块来进行处理；如果第一接口和第二接口的传输带宽受限，即如果第一接口和第二接口最多能够同时传输的信号的数量为a，则射频模块可以分时将该n个通道输出的n个信号传输到基带模块来进行处理，具体地，射频模块可以将该n个通道划分为b组，该b组通道中的每组通道的通道数量均为a，之后，在一段时间内将该b组通道中的第1组通道中所有的通道输出的信号传输到基带模块，再在下一段时间内将该b组通道中的第2组通道中所有的通道输出的信号传输到基带模块，以此类推，直至在某一段时间内将该b组通道中的第b组通道中所有的通道输出的信号传输到基带模块后，可以在下一段时间内再次将该b组通道中的第1组通道中所有的通道输出的信号传输到基带模块，如此循环。
再者，在发射信号的情况下，在尚未确定出目标合路策略和目标合路策略的m组合路系数时，可以从该多个合路策略中选择一个合路策略作为默认的合路策略，并依据经验或这个默认的合路策略的历史合路系数来为这个默认的合路策略设置m组合路系数，然后，使用这个默认的合路策略及其m组合路系数来进行分路处理。或者，可以在该n个通道中选择m个通道，基带模块将生成的m个信号传输到射频模块后，射频模块可以将该m个信号一一通过该m个通道进行发射。
在本申请实施例中，在采集周期内，先获取射频模块中的n个通道中每个通道对应的信道状态信息，再根据该n个通道对应的信道状态信息，确定多个合路策略中每个合路策略的m组合路系数，然后根据该n个通道对应的信道状态信息和该多个合路策略中每个合路策略的m组合路系数，从该多个合路策略中确定目标合路策略。之后，在第一处理周期内，按照目标合路策略和目标合路策略的m组合路系数，对该n个通道输出的n个信号进行合路处理，得到m个第一信号，通过基带模块对该m个第一信号进行处理。并且，在第二处理周期内，根据目标合路策略和目标合路策略的m组合路系数，对基带模块输出的m个信号进行分路处 理，得到与该n个通道一一对应的n个第二信号，然后将该n个第二信号中的每个第二信号通过该n个通道中对应的通道进行发射。如此，提供了一种灵活的通道配置方案，在不增加额外的硬件成本，不带来额外的损耗的情况下，可以将射频信号中输出的n路信号切换为m路信号，且可以将基带模块中输出的m路信号切换为n路信号，从而不仅可以满足基带模块的通道处理要求，而且可以充分利用射频模块的收发资源。
