技术领域
本公开实施例涉及通信技术领域，尤其涉及一种信号收发装置和电子设备。
背景技术
目前，在5G非独立(non stand alone，NSA)组网架构中，终端设备的信号收发端通常配置有多根天线，同时，由于NSA组网架构中的4G基站和5G基站是共存的，因此，终端设备的信号收发端同时配置有4G天线和5G天线，从而使得终端设备能够通过4G天线和5G天线分别收发4G信号和5G信号。
然而，由于终端设备内部空间有限，使得终端设备中的4G天线与5G天线之间的间距较小，从而导致4G天线与5G天线之间产生干扰，进而导致4G天线接收到的4G信号失真，或者5G天线接收到的5G信号失真。
例如，当终端设备中的4G天线发送4G信号、且5G天线接收5G信号时，由于4G天线与5G天线之间存在干扰，从而导致终端设备中的5G天线在接收到5G信号的同时还会接收到4G天线所发出的干扰信号，进而导致5G天线接收的5G信号失真。
发明内容
本公开实施例提供一种信号收发装置和电子设备，以解决终端设备中多个天线之间存在信号干扰的问题。
为了解决上述技术问题，本公开实施例是这样实现的：
第一方面，本公开实施例提供了一种信号收发装置，该装置包括：第一收发模块、第二收发模块、第一天线、第二天线以及信号处理模块，其中：第一收发模块的输出端与信号处理模块的输入端连接；信号处理模块的第一输出端与第一天线连接，信号处理模块的第二输出端与第二收发模块的输入端和第二天线之间的传输通道连接；第二收发模块与第二天线连接；
信号处理模块，用于将第一收发模块发送至信号处理模块的第一信号拆分为两路第一信号，第一信号包括干扰信号，还用于通过第一输出端将第一路第一信号发送至第一天线，以及获取并调节第二路第一信号中的干扰信号，并通过第二输出端向第二收发模块的输入端发送调节后的干扰信号；
第二收发模块，用于接收第二天线接收的第二信号中的第一目标信号；
其中，第二信号包括第一天线耦合至第二天线的第一路第一信号中的干扰信号，第一路第一信号中的干扰信号的相位与调节后的干扰信号的相位相反、且第一路第一信号中的干扰信号的幅度与调节后的干扰信号的幅度相同，以使第一路第一信号中的干扰信号在传输通道中与调节后的干扰信号对消。
第二方面，本公开实施例还提供了一种电子设备，该电子设备包括第一方面提供的信号收发装置。
在本公开实施例中，通过在相关的信号收发装置中增加一个信号处理模块，从而使得该信号收发装置能够解决该信号收发装置中第一天线与第二天线之间存在的信号干扰问题。即信号处理模块通过对第一收发模块发送至该信号处理模块的第一信号中的干扰信号进行调节，使得该信号处理模块能够向第二收发模块的输入端与第二天线间的传输通道发送调节后的干扰信号，由于该调节后的干扰信号的相位与该第一信号中的干扰信号的相位相反、且该调节后的干扰信号的幅度与该干扰信号的幅度相同，从而在第一天线将第一信号中的干扰信号耦合至第二天线时，使得该干扰信号能够在该传输通道中与该调节后的干扰信号对消，进而使得第二收发模块能够接收到第二天线所接收的第一目标信号，避免了第一天线耦合至第二天线的干扰信号对第一目标信号的干扰。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
图1为相关典型的4G天线与5G天线共存(即4G信号和5G信号不共用天线)的4G+5G双连接的信号收发装置的结构示意图，如图1所示，该信号收发装置100包括4G射频收发器101、5G射频收发器102、第一功率放大模组103、第二功率放大模组104，双工器105、第一射频开关106、第二射频开关107、第一耦合器108、第二耦合器109、4G天线110以及5G天线111，其中：上述的4G射频收发器101、第一功率放大模组103、双工器105、第一射频开关106、第一耦合器108以及4G天线110依次连接，并且上述的第一耦合器108与上述的4G射频收发器101连接；上述的5G射频收发器102、第二功率放大模组104、第二射频开关107、第二耦合器109以及5G天线111依次连接，且上述的第二耦合器109与上述的5G射频收发器102连接。
示例性的，上述4G射频收发器101用于接收或发送4G信号；上述的5G射频收发器102用于接收或发送5G信号；上述的第一功率放大模组103以及第二功率放大模组104用于放大信号的功率；上述的双工器105用于隔离4G射频收发器101发送的4G信号和4G天线接 收到的4G信号；上述的第一射频开关106用于实现4G信号的接收与发送的切换，上述的第一射频开关106还用于实现不同4G频段间的切换；上述的第二射频开关107用于实现5G信号的接收与发送的切换，上述的第二射频开关107还用于实现不同5G频段间的切换；4G天线110用于将4G射频收发器101发出的4G信号传输至4G基站，或者，用于接收4G基站传输的4G信号；上述第一耦合器108用于监控4G信号的功率，反馈至4G射频收发器101；上述第二耦合器109用于监控5G信号的功率，反馈至5G射频收发器102。
示例性的，以4G射频收发器101发送4G信号、且5G射频收发器102接收5G信号为例，4G射频收发器101在产生4G原始信号的同时，会产生二次谐波(即干扰信号)，即4G射频收发器101产生的4G信号中包含：4G射频收发器101产生的4G原始信号和上述干扰信号，该4G信号通过第一耦合器108耦合至4G天线110后，4G天线110会将4G原始信号发送至对应的4G基站。同时，若该干扰信号的频率刚好落在5G天线111接收5G信号的接收频段中，则4G天线110会将该干扰信号耦合至5G天线111，从而使得5G天线111在接收5G原始信号的同时，还会接收到上述的干扰信号，该干扰信号会对该5G原始信号造成干扰。
例如，当终端设备工作在4G B3频段(即上行频率为：1710MHz至1785MHz，下行频率为：1805MHz至1880MHz)时，假设4G射频收发器101在产生频率为1750MHz的一次谐波的情况下，还产生了频率为3500MHz的二次谐波。若终端设备同时工作在5G N77频段(即上行频率和下行频率均为：3300MHz至4200MHz)，则该二次谐波的频率刚好落在终端设备接收5G信号的频段中，因此，终端设备会同时接收5G信号和该二次谐波，该二次谐波会对终端设备接收的5G信号造成干扰。
为了解决上述问题，本公开实施例提供了一种信号收发装置，通过在相关的信号收发装置中增加一个信号处理模块，从而使得该信号收发装置能够解决该信号收发装置中第一天线与第二天线之间存在的信号干扰问题。即信号处理模块通过对第一收发模块发送至该信号处理模块的第一信号中的干扰信号进行调节，使得该信号处理模块能够向第二收发模块的输入端与第二天线间的传输通道发送调节后的干扰信号，由于该调节后的干扰信号的相位与该第一信号中的干扰信号的相位相反、且该调节后的干扰信号的幅度与该干扰信号的幅度相同，从而在第一天线将第一信号中的干扰信号耦合至第二天线时，使得该干扰信号能够在该传输通道中与该调节后的干扰信号对消，进而使得第二收发模块能够接收到第二天线所接收的第一目标信号，避免了第一天线耦合至第二天线的干扰信号对第一目标信号的干扰。
本公开实施例中所提及的“对消”，是指利用射频干扰对消技术将两个相位相反、幅度相同的信号相互抵消。其中，上述的射频干扰对消技术是指：利用矢量的合成叠加原理，将干扰信号比作直角空间坐标系中的一个矢量，通过找到一个与该矢量具有相同信息特征(如，信号的幅度)的反相矢量，即找到一个与该干扰信号相位相反、幅度相同的信号，将这两个矢量合成，从而抵消掉该干扰信号。
需要说明的是，上述的幅度相同的信号是指两信号的幅度间的绝对差值大于或等于0、且小于或等于预定阈值，即两信号的幅度可以趋于相同。
例如，矢量A为干扰信号，矢量B为与矢量A具有相同信息特征的等幅度反相矢量，用于抵消干扰信号，对这两者进行合成叠加，得到的矢量C趋于零，即干扰信号几乎消失。可以理解的是，“对消”的过程就是矢量A与矢量B合成叠加的过程。
本公开实施例中所提及的“耦合”，是指两个或两个以上的电路元件或电网络的输入与输出之间存在紧密配合与相互影响，并通过相互作用从一侧向另一侧传输能量的现象。例如， 4G天线将干扰信号耦合至5G天线的过程，相当于4G天线将干扰信号传输至5G天线。

第一实施例：
下面将结合附图对本公开实施例提供的信号收发装置进行详细描述。
图2为本公开的实施例提供的一种信号收发装置的结构示意图，如图2所示，该信号收发装置200包括：第一收发模块201、第二收发模块202、第一天线203、第二天线204以及信号处理模块205，其中：第一收发模块201的输出端201b与信号处理模块205的输入端205a连接；信号处理模块205的第一输出端205b与第一天线203连接，信号处理模块205的第二输出端205c与第二收发模块202的输入端202a与第二天线204间的传输通道连接；第二收发模块202与第二天线204连接。

示例性的，上述的第一信号还包括：第二目标信号，该第二目标信号为上述的第一收发模块201所产生的原始信号，而上述的干扰信号通常为第一收发模块201在产生第二目标信号的同时所生成的二次谐波或者其他高次谐波。

示例性的，上述信号处理模块205在调整干扰信号时，可以按照目标相位偏移量调整第二路第一信号中的干扰信号的相位，并按照目标幅度偏移量调整第二路第一信号中的干扰信号的幅度。其中，上述的目标相位偏移量可以为预定阈值，也可以按照实际应用场景灵活设定，本公开对此不作限定，同时，上述的目标幅度偏移量可以为预定阈值，也可以按照实际应用场景灵活设定，本公开对此不作限定。需要说明的是，上述的目标相位偏移量以及目标幅度偏移量可以是通过对干扰信号在该信号处理装置中传输的过程进行仿真而得到的。

需要说明的是，由于耦合器一般会移相0～90度，因此，本公开中的信号处理模块需要使得该第二路第一信号中的干扰信号相位从耦合器的耦合端(即分路单元的输入端)传输至5G RX传输通道(即第二收发模块的输入端和第二天线之间的传输通道)正好移相180度。

可选地，在本公开实施例中，结合图2，如图8所示，上述信号收发装置200还包括：第二功率放大器207，其中，第二功率放大器207的输入端207a与第一收发模块201的输出端201b连接，第二功率放大器207的输出端207b与信号处理模块205的输入端205a连接。
举例说明，结合图8以及图6，如图9所示，以分路单元2051为耦合器(即图9中的第三耦合器)、第一收发模块201为4G射频收发器、第二收发模块202为5G射频收发器、第一天线203为4G天线、第二天线204为5G天线、延时单元2053为延时器为例，在图6以及图8所示的信号收发装置的结构的基础上，该信号收发装置还包括：第二功率放大模组208、双工器209、第一射频开关210、第一耦合器211、第二耦合器212、第二射频开关213以及控制器214，其中：
示例性的，上述4G射频收发器201用于接收或发送4G信号；上述的5G射频收发器202用于接收或发送5G信号；上述的第一功率放大模组206、第二功率放大模组208以及第二功率放大器207用于放大信号的功率；上述的双工器209用于隔离4G射频收发器201发送的4G信号和4G天线203接收到的4G信号；上述的第一射频开关210用于实现4G信号的接收与发送的切换，上述的第一射频开关210还用于实现不同4G频段间的切换；上述的第二射频开关210用于实现5G信号的接收与发送的切换，上述的第二射频开关213还用于实现不同5G频段间的切换；上述第一耦合器211用于监控4G信号的功率，反馈至4G射频收发器201；上述第二耦合器212用于监控5G信号的功率，反馈至5G射频收发器202；上述控制器214用于控制4G射频收发器201和5G射频收发器202收发信号，还用于控制移相器20522的移相度数和衰减器20523的衰减值。
示例性的，当4G射频收发器201发出4G信号时，该4G信号中包含4G射频收发器201发出的4G原始信号和干扰信号，该4G信号经过第二功率放大器207进行功率放大后传输至第三耦合器2051，第三耦合器2051在将4G信号分路后，其中一路4G信号会通过4G天线203输出，另一路4G信号会通过第一滤波器20521滤除4G信号中的4G原始信号，以得到4G信号中的干扰信号，该干扰信号通过移相器20522进行移相，接着通过衰减器20523进行幅度衰减，最后经延时器2053延时后，会将调节后的干扰信号传输至5G信号的接收通道中。
移相器对干扰信号的相位进行移相的标准是：使得干扰信号经过路径1到B点的相位与干扰信号经过路径2到B点的相位相差180度。此外，衰减器在对干扰信号的幅度进行衰减 的标准是：需要满足路径1与路径2的损耗相同，即在路径1必须加上合适的幅度衰减值，以使干扰信号经过路径1到B点的幅度与干扰信号经过路径2到B点的幅度相等。具体的，如图9所示，从A点到B点的两条路径分别为路径1和路径2，其中：路径1为：A点-第三耦合器-第一滤波器-移相器-衰减器-延时器-B点；路径2为：A点-第三耦合器-双工器-第一射频开关-第一耦合器-4G天线-5G天线-第二耦合器-第二射频开关-B点。
应注意的是，上述的衰减器的衰减值与4G天线和5G天线之间的距离有关，可以通过仿真路径1中从A点到B点的能量衰减，以及结合该信号收发装置实际对5G信号的接收灵敏度，来确定出上述的衰减值。需要说明的是，不同频带下，衰减器的衰减值可以按照频带的不同进行适当调整。
应注意的是，由于第三耦合器一般会移相0～90度，因此，移相器对干扰信号的移相度数需要结合第三耦合器的移相度数进行移相。
例如，假设第三耦合器的对干扰信号移相的度数为85度，通过对干扰信号从路径1的A点到B点的移相仿真，如果干扰信号经过路线1到达B点的仿真过程中总共移相0.8度，如，第一滤波器移相0.5度，衰减器移相0.2度，延时器移相0.5度，路径2理想的状态下是没有任何移相的，因此，移相器需移相的度数为：180-85-0.8-0.5-0.5-0.2＝93度。
例如，假设通过仿真或者测试确定干扰信号在路径2中的A点到干扰天线的衰减值为2dB(分贝)，假设通过仿真或者测试确定干扰信号在路径2中的5G天线到B点的衰减值为1dB，假设4G天线到5G天线的隔离度为30dB。该干扰信号在路径2中的衰减值为33dB+3dB＝33dB，即该干扰信号从A点通过4G天线和5G天线耦合至B点的过程中能量衰减了33dB。假设通过仿真或测试确定干扰信号在路径1中总共损耗为3dB，那么衰减器的衰减值为33dB-3dB＝30dB。
本公开实施例提供的信号收发装置，通过在相关的信号收发装置中增加一个信号处理模块，从而使得该信号收发装置能够解决该信号收发装置中第一天线与第二天线之间存在的信号干扰问题。即信号处理模块通过对第一收发模块发送至该信号处理模块的第一信号中的干扰信号进行调节，使得该信号处理模块能够向第二收发模块的输入端与第二天线间的传输通道发送调节后的干扰信号，由于该调节后的干扰信号的相位与该第一信号中的干扰信号的相位相反、且该调节后的干扰信号的幅度与该干扰信号的幅度相同，从而在第一天线将第一信号中的干扰信号耦合至第二天线时，使得该干扰信号能够在该传输通道中与该调节后的干扰信号对消，进而使得第二收发模块能够接收到第二天线所接收的第一目标信号，避免了第一天线耦合至第二天线的干扰信号对第一目标信号的干扰。
