Abstract :
Turbo-TCM is a bandwidth-efficient coded- modulation scheme, which has near-capacity performance on the AWGN channel. It has an overall structure similar to binary Turbo codes, but employs Trellis Coded Modulation (TCM) codes as component codes. In this paper, we propose a novel coded-modulation scheme, which is a combination of Turbo codes with MTCM, called Turbo-MTCM. The Turbo-MTCM scheme which is designed for optimum performance on the AWGN channel obtains performance gain over Turbo-TCM on the AWGN channel, with the same number of trellis state and spectrum efficiency.
