Using Turbo TCM in Image Transmission over Rayleigh Fading Channels

초록

In this paper, based on the characteristics of Turbo Codes and Trellis Coded Modulation (TCM), a improved method Turbo Trellis Coded Modulation (Turbo TCM, 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 8PSK modulation of Turbo TCM as the example, two performance of image transmission in Rayleigh fading channels is showed.
