跳频扩时光码分多址系统误码率上限的研究

Investigation of Upper-Bounds on BER of OCDMA Systems Using Time Spreading/Wavelength Hopping Codes

在对跳频扩时光码分多址系统是否使用光学硬限幅器的误码率上限进行理论分析的基础上,通过仿真给出了误码率随影响系统性能的各个参数以及有无光学硬限幅器时的变化曲线,并给出了相应的分析,得到了结果:减少码片之间的碰撞概率以及使用光学硬限幅器能有效地改善系统的性能。

The upper-bounds on BER of OCDMA systems using the time spreading/wavelength hopping codes is investigated with or without using the optical hard limiter.The thorough investigation and analysis on the performances of the systems is performed by simulation and it gets some valuable results. Reducing hit probability between codes and using optical hard limiter can effectively improve the performances of the system.
