COMPARISON OF RECEIVERS FOR MULTI-H CPM

Abstract

A noncoherent receiver for the general case of M-ary partial response multi-h continuous phase modulation (CPM) is presented. The receiver operates on the principle of sequence estimation via the Viterbi Algorithm (VA). It offers a significant complexity reduction from the optimal coherent maximum likelihood sequence estimating (MLSE) receiver. The performance of the receiver is evaluated with computer simulations. It performs at a loss of 1–6 dB relative to the MLSE receiver for the CPM schemes considered in the simulations. The receiver shows promise in applications requiring reduced complexity and use of existing hardware.
