After the derivation of the formula of symbol error rate versus average transmitted power for uncoded 256-ray PPM,the symbol error rate of Turbo coded PPM and uncoded PPM are simulated and analyzed,and also that of laser with two different wavelengths.

在推导了未编码256-ray PPM的符号差错率相对平均发射功率的关系式之后,仿真分析了Turbo码编码PPM与未编码PPM的符号差错率以及850nm和1550nm两种波长激光的符号差错率。

To study the concept of Overlapping Time Division Multplexing(OvTDM),the implemented waveform is proved analytically to be the one that determines the symbol error ratio(SER) of the system based on the existing upper bound.

为了深入研究重叠时分复用系统,通过已有的理论界推导了影响系统符号差错概率的关键因素,由此解析地研究了指数波形、高斯波形和矩形波形对重叠时分复用符号差错概率的性能影响。
