摘　　要：利用多相滤波器组的成熟理论推导出一种高效的宽带数字信道化接收机结构,并且结合瞬时测频技术,可以实现多通道信号全概率适时接收的跨信道判决,避免虚假信号的产生。利用Matlab进行了仿真测试和验证,仿真结果证明了该实现方法的可行性和有效性。An architecture of a broadband digital channelized receiver was deduced with the mature theory of DFT polyphase filter banks. The cross-channel decision for receiving the multi-channel signals with total probability at the right time can be achieved in combination with the instantaneous frequency measurement technology to avoid the false signal generation. The simulation testing and verification were performed with Matlab software. The simulation result indicates that the method is feasible and effective.
