Model of Non-leaking-alarms and Non-aliasing Channelized Digital Receiver
Because the ability of handling multiple signals at the same arriving time and has a high intercept probability,wideband Channelized receiver has become a hot research topic in domestic and foreign.Channelized receiver based on polyphase filtering has less computational and more channels.In this paper,a new efficient structure model based on real signal non-maximally decimated channelization is derived,it has a wide applicability,and we analyzed the advantages and disadvantages of this model.The leaking-alarming phenomenon of the channelized receiver is discussed in this paper.In this paper,the aliasing phenomenon caused by part-overlapping polyphase filtering structure is solved by a new method of extending the processing bandwidth.Simulation analysis for the nonmaximally decimated non-leaking-alarming and non-Aliasing channelized digital receiver model presenting by this paper,the consequence of the simulation confirms the model is accurate and reliable.
