Abstract:

In the complex electromagnetic environment of modern electronic war,a military receiver requires the ability to handle multiple channel signals,namely full probability interception.Channelized receiver can divide a complex signal into multiple channels,so as to facilitate the subsequent processing.This paper uses a simplified structure to verify the feasibility of this channelized scheme,which saves logic resources.
