【摘要】 研究了基于布喇格光纤光栅的FFH-OCDMA系统的性能。在系统中放置双硬限幅器,考虑码片异步(即系统下限情况),采用在接收端的散粒噪声服从泊松分布的研究模型。仿真结果表明:与不考虑光纤的色散和非线性效应时对系统性能的影响相比,系统误码率恶化了约105倍。更多还原

【Abstract】 The performance of asynchronous FFH-OCDMA system with double hard-limiters based on fiber optical Bragg grating is studied under the assumption of Poisson shot noise model for receiver photo-detector. The numerical result demonstrates that the performance of the system is deteriorated by 105, considering the dispersion and nonlinearly effect of the transmission medium.更多还原
