Two four-state trellis-coded modulated (TCM) codes for Rayleigh fading channels, which perform significantly better than the best additive white Gaussian noise (AWGN) channel codes previously published, are presented.Abstract:
The performance of trellis codes on a Rayleigh fading channel is presented. Performance of good Gaussian channel codes is assessed by means of a simulation. Two four-state trellis-coded modulated (TCM) codes for Rayleigh fading channels, which perform significantly better than the best additive white Gaussian noise (AWGN) channel codes previously published, are presented. The best four-state code achieves a 5.8-dB gain at an error rate of 10/sup -2/ as opposed to the 3.7-dB gain achieved by the Gaussian channel code. >read more

Channel coding with multilevel/phase signals
TL;DR: A coding technique is described which improves error performance of synchronous data links without sacrificing data rate or requiring more bandwidth by channel coding with expanded sets of multilevel/phase signals in a manner which increases free Euclidean distance.

TL;DR: Simple two-state trellis codes for symmetric MPSK multiple phase-shift keying and AM modulations that can achieve 3-dB gain over uncoded modulation at very high signal-to-noise ratios without bandwidth expansion or reduction in information bit rate are found.
