Evaluation of trellis coded modulation effects in time-selective fading mobile radio channel

Abstract

In this paper effects of trellis coded modulation in mobile radio systems are evaluated. The specific channel with timeselective fading process is considered. The complete descriptions of such channel and an appropriate receiver is given. General model for bit error rate calculations is presented. That model enables error determination for every type of fading encountered in mobile radio systems as well as for different TCM schemes. Here we chose to analyse trellis encoding in combination with PSK, PSK with pilot tone and DPSK.
