摘　　要：从距离谱的角度对迫零在Turbo码中的作用进行了理论分析。通过仿真 ,研究了迫零对Turbo码性能的影响。仿真结果表明 ,Turbo码编码器迫零处理有助于改善Turbo码的性能。The role of trellis termination in turbo codes is analyzed in point of the influence of trellis termination on the distance spectrum. The influence of trellis termination on the performance of turbo codes is studied by simulation. The simulation results show that turbo codes with trellis termination outperformed those without trellis termination.
