A LINEAR PAM-BASED RECEIVER FOR MULTI-H CPM

Abstract

A linear pulse-amplitude modulation (PAM) receiver for the ARTM Tier II multi-h waveform is presented. The receiver is optimal and can be implemented using maximum likelihood sequence estimation (MLSE). The linear signal model also allows many attractive complexity reductions. The performance of these reduced-complexity receivers is evaluated via computer simulation. One simplified receiver consists of three matched filters and a 32-state Viterbi trellis and is shown to perform with a 1:5 dB degradation relative to the optimal receiver.
