Abstract :
This paper presents a new coding scheme based on the association of a turbo-code with a bandwith efficient modulation. It is shown that the new coding scheme provides a substantial coding gain both on Gaussian channels and Rayleigh channels. On a Gaussian channel, it outperforms 64-state trellis-coded modulation (TCM) by 2.5 dB at the bit error rate (BER) of 10-6. On a Rayleigh fading channel, it outperforms 64-state TCM optimized for that environment
