摘要：
This paper deals with a new receiver scheme that combines Turbo Equalization and Turbo Trellis Coded Modulation (TTCM). This receiver serially concatenates a soft input soft output (SISO) equalizer and a soft-out symbol-by-symbol MAP TTCM decoder through an iterative process. In certain cases, the joint Turbo Equalization and TTCM scheme can totally overcome the channel frequency selectivity and obtain high bandwidth efficiency and more coding gains. This scheme has modest complexity since a suboptimal reduced-state MAP equalization algorithm and simple TTCM component codes are employed. Simulation results show that this receiver can achieve comparable performance with TTCM receiver on a non-selective Gaussian channel with coding.
