Abstract

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 pre-sented and analyzed over flat Rayleigh fading channels in image transmission with two typical mapping strategies. The selection of different mapping strategies of TTCM in Rayleigh fad-ing channels for image transmission is analyzed and investigated. Furthermore, taking 8PSK modulation of TTCM as the example, two different mapping strategies are compared. Com-puter simulation results and PSNR that can evaluate the quality of the transmitted image are given.
