以下结合附图对本发明进行详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不限定本发明。在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
在本实施例中，提供了一种通信抗干扰检测方法，图6是根据本发明实施例的无线通信抗干扰检测整体流程框架示意图，如图6所示，具体步骤如下。
A101第一天线和/或第二天线接收到的射频信号经过A102耦合器，通过B100抗干扰检测模块，判断其值是否为零或信号是否存在干扰，控制B300逻辑控制开关，如SP2T开关，如果值为零或不存在干扰，直接控制A102耦合器，接收到的射频信号直接通过D101射频电路进行处理；如果值不为零或存在干扰，那么干扰信号通过C100抗干扰模块进行滤出，最后将有用信号调制到射频信号经过D101射频电路处理。
在本实施例中，图7是根据本发明实施例的无线通信抗干扰检测系统详情框架示意图，如图7所示，具体步骤如下。
A101第一天线和/或第二天线接收到的射频信号经过A102耦合器到A103衰减器，通过A104解调器后的信号进行B101傅里叶逆变换成不同频率的正弦波的叠加，同B201存储器中B202反相器倒相后的特定的基带信号经B102卷积器进行卷积，判断其值是否为零或信号是否存在干扰，控制B300 逻辑控制开关，如SP2T开关，如果为零或不存在干扰，直接控制A102耦合器，接收到的射频信号直接通过D101射频电路进行处理；如果卷积值不为零或存在干扰，那么干扰信号通过C110抗干扰电路进行滤出，再经C120傅里叶变换和C130调制器最后将有用信号调制到射频信号经过D101射频电路处理。
在本实施例中，提供了一种通信抗干扰检测方法，以下是一种实施例，说明本发明方法的一种应用场景示例，进一步阐释本发明，并不对本发明方法做任何限制。例如，Band 41全频段带宽196MHz，按照目前某运营商的需求(Sub6G 100MHz，LTE 60MHz)划分，Sub6G N41与LTE Band41频段中间保护带宽只有36MHz。Sub6G发射时，其边带噪声可能会落入LTE的接收带内；同理，LTE发射时，LTE的边带噪声也可能会落入Sub6G的接收带内。
如图6、图7所示，4G和5G通信同时工作，当N41工作在A101第一天线时，B41工作在第二天线，两信号进入开关后分别经过A103衰减器，A104解调器，将射频信号解调后的信号进行傅里叶逆变换成不同频率的正弦波的叠加，同存储器中特定的信号倒相后卷积，得到卷积后的干扰信号，通过比较器判断卷积后的信号是否为零或是否存在干扰，如果不为零或存在射频干扰，控制SP2T开关，经过附加的C110抗干扰电路，将接收到的N41的信号和反卷积器得到的干扰信号进行反相叠加后滤出，然后将有用信号调制到射频信号。
多制式通信同时工作时，两个频段间可能存在干扰。当其中一个制式工作在第一天线时，另一个制式工作在第二天线，两信号进入耦合器后分别经过衰减器，解调器，将射频信号解调后的信号进行傅里叶逆变换成不同频率的正弦波的叠加，然后和存储器中特定的倒相信号进行卷积，除去有用正弦波信号，得到的卷积后的干扰信号，判断是否存在干扰。傅里叶变换公式如下
Figure PCTCN2020081197-appb-000001
称为f的傅里叶变换,记为卷(u)。在一些书中，积分前面的因子用代替，假定函数f∈(-∞,∞)，所以上式中的积分是存在的。
如果存在干扰，将控制SP2T开关打开抗干扰电路，卷积后的干扰信号经过反卷积器后与傅里叶变换的信号相减，从而滤出干扰信号，最后将有用信号调制到射频信号；如果不存在干扰，直接控制从SP2T开关到射频电路。
在一实施例中，所述干扰检测模块包括了衰减器、解调器、傅里叶逆变换模块、卷积器和存储器模块。
在一实施例中，所述的傅里叶逆变换模块需要将解调后的射频信号变换成不同频率的正弦波的叠加。
在一实施例中，所述天线电路包括2G、3G、4G、5G、6G天线。
在一实施例中，所述抗干扰电路包括反卷积器和减法器。
在一实施例中，在本实施例中，提供了一种通信抗干扰检测方法，以下是一种实施例，说明本发明方法的一种应用场景示例，进一步阐释本发明，并不对本发明方法做任何限制。例如，Band 7的发射频段是2500MHz-2570MHz，而WIFI 2.4G的频段是2400MHz-2483MHz，两个频段同时工作时，频段间的保护带宽是17MHz。当Band7发射时，其边带噪声可能会落入WIFI 2.4G的接收带内；同理，WIFI 2.4G发射时，其边带噪声也可能会落入Band7的接收带内。
如图6、图7所示，LTE和WIFI通信同时工作，当LTE工作在第一天线时，WIFI工作在第二天线，两信号进入开关后分别经过衰减器，解调器，将射频信号解调后的信号进行傅里叶逆变换成不同频率的正弦波的叠加，
其中C就是上面提到的所述直流分量，an和bn就是不同频率的正弦的幅度，同存储器中特定的信号倒相后卷积，得到卷积后的干扰信号，通过比较器判断卷积后的信号是否为零，如果不为零就确实存在射频干扰，控制SP2T开关，经过附加的抗干扰电路，将接收到的LTE Band7的信号和反卷积器得到的干扰信号进行反相叠加后滤出，然后将有用信号调制到射频信号。
以上所述仅为本发明应用于5G手机等无线终端接入产品一个实施例而已，凡在本发明方法的精神和原则之内，不同制式频段组合以及连接方式的变换等方面所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
