Non-maximally Decimated Filter Bank for Wideband Channeizer
Channelizer filter banks play an important role in software defined radio.For wideband channelizers maximally
decimated filter bank is suggested. We have shown how an analysis-synthesis filter bank can be used for channelization
application. It comprises of analysis filter bank and synthesis filter bank. We also show how analysis filter bank can be
derived from a single low pass filter. The results show how different bandpass responses are obtained from prototype low
pass filter. We also discuss applications of non maximally decimated filter bank.
