Polyphase filter bank channelizer
WebApr 12, 2013 · The polyphase filter bank algorithm is a very efficient way to implement a uniformly distributed multichannel filter bank using a fast Fourier transform. In standard channelizer. The reconfigurability of the receiver is accomplished by switching among different Filter banks, each designed for a particular standard. WebThe Channelizer block separates a broadband input signal into multiple narrow subbands using an FFT-based analysis filter bank. The filter bank uses a prototype lowpass filter …

In this paper, the design of non-uniform Modified Discrete Fourier Transform filter bank (MDFT FB) is proposed to be used in SDR channelizer. The frequency response masking technique is used to design the prototype …
WebIn this paper, the problem of how to realize an multi-channel receiver with various bandwidth is discussed in details. After a channel spectrum partition is given, a mathematic model of channelized receiver is derived, based on polyphase filter. Then a simulation system is designed. All the simulation results show that the presented model is valid and practical.
