WIDEBAND CHANNELIZATION USING SUBSAMPLED DISCRETE FOURIER TRANSFORMS

摘要

A receiver and channelizer for processing a wideband signal is disclosed. The channelizer consists of a receiver for receiving a wideband signal. The received wideband signal is processed by a subsampled DFT-channelizer to extract a selected number of regularly spaced channels from a plurality of channels within the received wideband signal. These extracted regularly spaced channels are then output for further processing by a receiver.
