相位分集频移键控光通信系统中码间干扰的研究

Intersymbol Interference in Optical Phase Diversity FSK Communication Systems

本文分析了码间干扰(ISI)对相位分集频移键控(PD-FSK)光通信系统特性的影响,导出了由于ISI引起的系统功率代价的解析表达式,并考虑到典型的系统参数值,分析比较了功率代价与系统参数的关系。

The effect of intersymbol interference (ISI) in optical phase diversity FSK (PD-FSK) sys-tems is analyzed. The expressions of the associated power penalty resulting from ISI are proposed for the first. The relation between the power penalty and the system parameters is studied with typical parameter values.
