Abstract

A novel variety of the polyphase method (PPM) for digital demultiplexing of an L₀-channel FDM (frequency-division multiplexed) signal is derived, and a design example of an application onboard a future communications satellite is given. This PPM applies bandpass sampling and is based on the processing of analytic signals by linear-phase FIR (finite-impulse-response) filters with complex coefficients, where at any stage of processing the respective signals are always oversampled by two. For L₀=32 it is by one order of magnitude more efficient than the original approach of E. Del Re and P.L. Emiliani (1982), which was based on analytic signal processing
