Modelling and Simulation of Digital Channelized Receiver Based on IDFT Poly-phase Filter Architecture

摘要

This paper presents an efficient architecture ofdigital channelized receiver based on IDFT poly-phase filterbank. The proposed architecture has broadband instantaneousfrequency coverage, small amounts of calculation, highfrequency resolution, and strong capability to distinguishsimultaneous signals. This architecture also provides a goodmodel for accurate instantaneous frequency measurement. Thesimulation results by Matlab indicate that it is highly efficient.
