Abstract :
Pragmatic trellis coded modulation (TCM) uses the industry standard, 64-state, binary convolutional code. The authors present the logic design and simulation results for a system which effectively implements pragmatic TCM for rate 2/3 encoded 8 phase shift keying (PSK). This system associates each sector of a quantized phase receiver with a pair of weights to be used as soft decision inputs of the Viterbi decoder. This system approaches 3 dB of coding gain at bit error rates of 10/sup -5/ and less.<>
