光OPPM-CDMA多脉冲检测接收机性能分析

根据光OPPM-CDMA信号格式和多脉冲检测接收机原理，使用概率并集域以及有两个判决量度相等也发生判决错误的悲观估计法获得基于任意λa、λc地址码（如光正交码、扩展二次同余码）的光OPPM-CDMA多脉冲检测接收机的误比特率上限，并比较了不同参数下OPPM-CDMA多脉冲检测接收机与OPPM-CDMA相关接收机的误码特性。

Analyses of a Multi-pulse Detection Receiver for Optical OPPM-CDMA

According to the transmitted signal formats of a single user and the multi-pulse detection receiver in an optical direction detection overlapping pulse position modulation code division multiple access system, the probability union bound and the pessimistic estimation methods that decision errors occur on condition that two decision measurements are equal are utilized to derive the upper bound on the bit error of OPPM-CDMA multi-pulse detection receiver for arbitrary la and lc signature codes such as optical orthogonal codes and extended quadratic congruence codes. Moreover, the performances of OPPM-CDMA multi-pulse detection receiver in terms of bit error is compared with those of traditional OPPM-CDMA correlation receivers with different parameters.
