WebWith the technologies of wireless communication like cognitive radio (CR), analysis filter banks (FBs) are used to adopt two crucial tasks; channelization followed by spectrum sensing. The channelizer is used to obtain separate channels from the wideband digital input signal at different intervals of time. Webtransform polyphase ﬁlter bank (DFT-PFB) [12], [15] is one of these ﬁlter banks that provides high computational efﬁciency. This digital structure makes use of a polyphase ﬁlter to isolate
