Performance and analysis of turbo TCM in image transmission over Rrayleigh fading channel

초록

In this paper, based on the characteristics of Turbo Codes and Trellis Coded Modulation (TCM), an improved method Turbo Trellis Coded Modulation (Turbo TCM,TTCM) is presented and analyzed over Rayleigh fading channel. We use three mapping strategies, UP (Ungerboeck Partitioning), BP (Block Partitioning) and MP (Mixed Partitioning) of TTCM in image recovering over flat Rayleigh fading channel. Furthermore, taking 8PSK modulation of TTCM as the example, results show that TTCM with UP can get better erformance than TTCM with BP, MP in flat Rayleigh fading channel.
