Design and simulation of wideband channelized receiver

Zhang Wenxu

Open publisher page 4 citations

Abstract

In order to solve the problem how to receive signals arriving simultaneously in electronic reconnaissance receiver, a no-blind area and efficient digital channelized receiving model is derived from traditional low-pass filter structure. CORDIC algorithm is adopted to realize the extraction of instantaneous amplitude and instantaneous phase after channelization. The phase difference algorithm is used to realize digital instantaneous frequency measurement. The model of channelization is verified correct by system simulation.
