Abstract :
In this paper, based on the characteristics of turbo codes and trellis coded modulation (TCM), an improved method turbo trellis coded modulation (TTCM) is presented and using it in still image transmission is also analyzed over Rayleigh fading channel. We use two mapping strategies of TTCM in Rayleigh fading channels UP (ungerboeck partitioning) and BP (block partitioning). Furthermore, taking 8 PSK modulation of turbo TCM as the example, two performance of image transmission in Rayleigh fading channels is showed.
