Abstract

In this paper, based on the characteristics of Turbo Codes and Trellis Coded Modulation (TCM), an improved method Turbo Trellis Coded Modulation (Turbo TCM) with two different mapping strategies is presented over AWGN (add white gauss noise) channels. The performance of different mapping strategies of Turbo TCM in AWGN channels for image transmission is analyzed and investigated. Furthermore, taking 16QAM modulation of Turbo TCM as the example, two different signal constellations are compared and computer simulation results are showed.
