| Abstract: | Considering the character of mobile satellite channel, TCM (Trellis codes modulation) technique becomes a useful method to solve contradiction between frequency band and power. In this paper, the succinct nonbinary MAP algorithm is derived, and the analytical performance of Turbo TCM technique is presented in mobile satellite channel. The simulation results show that Turbo TCM can achieve better performance than conventional TCM. |
