Abstract
A computationally efficient digital signal processing (DSP) system is provided for multiplexing/demultiplexing a large number of closely spaced FDM channels. Sub-band definition filtering divides the FDM channel band, comprised of N channels into K sub-bands, in order to reduce the dimension of polyphase filter fast-Fourier transform for completing the multiplexing/demultiplexing. This reduces the order of the required prototype by a factor proportional to K and allows small size, lightweight DSP implementations.
