FPGA Realization of Digital Channel Based on Polyphase Filters
Hou Cong · Telecommunication Engineering · 2012
Implementation of digital channelization is presented based on polyphase filters and structure of the uniform filters and 50% overlap of subchannels division.The contradiction between high-speed real-time processing and FPGA processing speed is solved,and the blind spot of the channelized receiver is overcome.The idea and method for implementing HF broadband digital channelization based on FPGA is proposed.Simulation shows the design has strong practicality and versatility.
