Abstract :
The application of new ring-TCM codes for QAM on the land mobile satellite channel is investigated. It is demonstrated that their intrinsic trellis structure makes them especially suitable for application on fading channels. Furthermore, a comparison between ring-TCM codes and the best known TCM codes for fading channels has revealed that they offer a significantly better tradeoff between actual coding gain and decoder complexity
