An Ameliorated Algorithm of Broad-band Digital Channelized Receiver Based on Polyphase Filter Banks
Xing Wang · Telecommunication Engineering · 2012
The real signal model based on polyphase filter banks and its advantages and disadvantages are discussed.First,for the problem of blind-zone and through reducing the multiple of decination,the algorithm is improved.Then,a mathematical model of no-blind-zone channelized receiver is derived.The two models are simulated respectively and the results show that both the improved algorithm and the ameliorated model are valid and practical.Adopting this improved algorithm can realize total probability interception and capturing of signals.
