FREQUENCY DOMAIN EQUALIZATION METHOD FOR CONTINUOUS PHASE MODULATED SIGNALS

摘要

A method for frequency domain equalization of a cyclic CPM signal received via a channel, comprising the steps of: representing the received cyclic CPM signal as a matrix model comprising a channel matrix representing influence of the channel, separate from a Laurent pulse matrix and a pseudocoefficient matrix respectively representing Laurent pulses and pseudocoefficients determined by Laurent decomposition of the received cyclic CPM signal; applying a channel equalizer on the separate channel matrix and after the equalization, demodulating the received cyclic CPM signal by means of the matrix model, the demodulation exploiting known correlation properties of the Laurent pulses and the pseudocoefficients.
