摘　　要：把网格编码调制(TCM)技术引入到光差分脉冲位置调制(DPPM)中,研究其对光DPPM系统误码性能的改善。通过对TC-16DPPM和8PPM的Matlab仿真分析得到以下结论:在保持带宽不变的前提下,TC-16DPPM与8PPM信息速率相同,但前者误码性能优于后者,且最大达到3dB。Trellis Coded Modulation（TCM）is introduced into DPPM to investigate the error performance improvement in optical Diffreencial Pulse Position Modulation（DPPM）systems.Theoretical deduction and MATLAB simulation and comparisons of TC-16DPPM with 8PPM respectively,produce the following results.When the bandwidth is kept constant,TC-16DPPM and 8PPM have the same information rate,but the error performance of the former is better than the latter,up to 3dB at the maximum.
