摘要
基于Turbo码和网格编码调制的特点 ,分析了TTCM(Turbo Trellis Coded Modulation)的具体编译码方法 ,比较了移动通信中TTCM在 8PSK调制下结合两种典型映射方案UP(Ungerboeck Partitioning)、BP(Block Partitioning)在平坦Rayleigh衰娩信道下的性能差异 。
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.
