Abstract
The authors investigate ring-TCM codes suitable for M-QAM signal sets on nonfrequency-selective fading channels. A new range of nonrotational invariant (NRI) and rotational invariant (RI) fading-optimised ring-TCM codes suitable for rectangular M-QAM schemes is presented. The trade off between the code gain and the decoder complexity of these codes is analysed, and their actual performance under different fading channel conditions is evaluated. In addition, a comparison with the best fading-optimised TCM codes for M-QAM reported in the literature is carried out
