Transceiver apparatus employing wideband fft channelizer and inverse fft combiner for multichannel communication network

Abstract From the Canadian patent

A physically compact, multichannel wireless communication transceiver architecture employs overlap and add or polyphase signal processing functionality, previously applied to narrowband speech analysis research, for wideband signal processing. A receiver section receives a plurality of multiple frequency communication channels and outputs digital signals representative of the contents of the plurality of multiple frequency communication channels. The receiver section contains an FFT-based channelizer that processes the digital signals output by a wideband digital receiver and couples respective channel outputs to a first plurality of digital signal processor units which, process (e.g. …
