A Wideband Digital Channelized Receiver Design

According to the characteristic of the digital channelized receiver,which must have the ability of processing the large number of data in real time,an efficient digital parallel analyzing system is introduced in this paper,and it adopts the multi-phase filter technology to implement channelization.Furthermore,by applying instantaneous frequency measurement algorithm to this system,we can get high estimation accuracy.Finally,the working processing of the whole receiver is described from mathematics model,the system is simulated in Matlab environment,and better results are received.
