Design and realization of an efficient channelized receiver

An efficient digital channelized receiver is introduced.A channelized receiver model for real signal is derived from traditional low pass filter structure to polyphase filter banks.The hardware platform of channelized receiver is set up and the chan- nelized receiver,which has 480MHz dual-channel instantaneous bandwidth and,960MHz single-channel instantaneous bandwidth is realized by using uniform filter banks division.The specific function structure for channelized receiver based on FPGA is given and the correctness of function,which includes channelized receiving,channel discrimination and instantaneous phase extraction,is veri- fied by Practical test for system.
