以下结合附图，对本发明实施例的上述技术方案继续详细说明。
图2是本发明实施例的FPGA中新增多个数字滤波器来实现各个制式载波的分离的示意图，图3是本发明实施例的具体实现示意图，如图2、图3所示，
本发明实施例的技术方案在FPGA中新增多个数字滤波器来实现各个制式载波的分离，从而检测各个制式的输出功率和驻波比。具体地，在实际应用中，数字中频部分主要由FPGA实现，由数字上变频模块、DPD以及数据采集模块和输出调整模块组成，在CPU和DSP控制下对数字化的IQ数据进行处理。
下面分别对功率检测和驻波比检测的处理继续详细说明。
1、功率检测：如图3所示，功放输出端通过耦合器反向输出端耦合出输出功率，这时的功率信号是射频模拟信号，经过混频器件后变成中频模拟信号，在通过数模转换器件(ADC)转换为中频数字信号，再经过数字滤波器分离出不同制式的功率，最后经过反馈功率检测模块，得到各制式的载波功率。
图4是本发明实施例的功率检测的具体处理流程图，如图4所示，具体包括如下处理：
步骤401，OMMB(网管系统)发起各制式功率诊断命令；
步骤402，操作人员预先在OMMB上配置各制式载波的中心频点(fc)、带宽(BW)和功率信息(Prat)，CPU控制模块将配置信息下发到FPGA模 块，前提是FPGA模块上软件开发人员会增加多个数字滤波器，对应各个制式载波的频点、带宽特性，并将这些数字滤波器封装成多个函数；
步骤403，软件会调用上述函数，并将滤波器的中心频点和带宽替换成配置的频点和带宽，就可以将各个制式的载波功率通过滤波器分离出来；
步骤404，将检测出的功率信息通过CPU控制模块送给OMMB显示。
2、驻波比检测：如图3所示，通过切换开关控制功放输出端耦合器的前向输出端和反向输出端的切换，在前向输出端接通的时候，耦合出前向功率，在反向输出端接通的时候，耦合出反向功率，通过混频器、ADC和数字滤波器之后的信号分别为各制式的前向功率和反向功率，再通过驻波比检测模块计算出各制式的驻波比。
图5是本发明实施例的驻波比检测的具体流程图，如图5所示，具体包括如下处理：
步骤501，OMMB(网管系统)发起各制式驻波比检测命令；
步骤502，操作人员预先在OMMB上配置各制式载波的中心频点(fc)、带宽(BW)和功率信息(Prat)，CPU控制模块将配置信号下发到FPGA模块，前提是FPGA模块上软件开发人员会增加多个数字滤波器，对应各个制式载波的频点、带宽特性，并将这些数字滤波器封装成多个函数；
步骤503，软件会调用上述函数，并将滤波器的中心频点和带宽替换成配置的频点和带宽，控制切换开关的方向，就可以将各个制式载波的前向功率和反向功率通过滤波器分离出来；再通过驻波比检测模块，就可以计算出各制式载波的驻波比；
步骤504，各制式载波的驻波比通过CPU控制模块发送给OMMB显示。
在本发明实施例中，具体判定故障方法：如果检测到的各制式功率突变为零，可以判断硬件链路是否出现异常；如果检测到的各制式数字功率和实际功率差别变大，可以判断单个制式配置、软件运行等是否出现问题。另外，由于各个制式载波带宽和功率不一样，也导致各个制式的驻波比会有差别，通过分别检测，也能更容易的发现一些问题。
下面以LTE和GSM双制式基站为例，说明如何检测两种制式的输出功 率和驻波比，并通过OMMB进行诊断查看。
1、操作人员通过OMMB发起功率诊断流程，FPGA通过CPU控制模块从OMMB获取配置的各个制式的中心频点和带宽信息，软件调用封装好的数字滤波器函数，并将配置信息传递给该函数，经过滤波处理后的各制式载波功率通过CPU控制模块发送给OMMB显示。
2、操作人员通过OMMB发起驻波比诊断流程，FPGA通过CPU控制模块从OMMB获取配置的各个制式的中心频点和带宽信息，软件调用封装好的数字滤波器函数，并将配置信息传递给该函数，控制切换开关的方向，分时得到前向功率和反向功率，经过滤波处理后的各制式载波的前向功率和反向功率，再通过驻波比检测模块计算出各制式的驻波比，通过CPU控制模块发送给OMMB显示。
综上所述，本发明实施例的技术方案的数字滤波器由相关技术的FPGA器件实现，不用增加硬件器件，只需修改软件代码，成本低，易于实现。
