Class of compact spectrum coded signals over multipath fading channel

Abstract

The author presents a trellis code coupled with a class of continuous phase modulation (CPM) signals over a multipath fading channel. Receiver structures for coherent, differentially coherent, and noncoherent detection are presented. Simulation results for the systems under consideration are shown. It is concluded that the differentially coherent system, though inferior in performance to the coherent system, offers the most feasible receiver structure for the trellis-coded CPM over a Rician fading channel.<>
