Abstract :
An efficient channelized structure of digital channelized receiver is derived and given in order to save a lot of resources of FPGA. The actual system is designed and CORDIC algorithm is adopted to realize the extraction of signal envelope and instantaneous phase and first order phase difference algorithm is used to realize instantaneous frequency measurement. The efficient channelized structure is verified correct by computer simulation and the function of instantaneous phase measurement and instantaneous frequency measurement is verified correct by system testing.
