Using turbo trellis coded modulation with two typical mapping strategies over rayleigh fading channels

An improved method for Turbo Trellis Coded Modulation (TTCM) is presented based on the characteristics of Turbo Codes and Trellis Coded Modulation (TCM), and using it in mobile communication were 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, the performance of TTCM with two mapping strategies in Rayleigh fading channels were showed.
