【摘要】 通过概率分析的方法,对工作于同步方式下的频谱相位编码光码分多址系统的统计特性进行了研究,据此给出了同步方式下系统的误码率特性及其数学表达式,并对工作于不同方式(随机方式和同步方式)下的系统的性能进行了蒙特卡罗仿真验证与比较.数值结果表明:在随机方式下,系统的误码率满足高速全光通信的需要;而在同步方式下,系统的误码率值太大,不能满足高速全光通信的需要.更多还原

【Abstract】 Using probabilistic method, this paper analyzed the statistical characteristics of synchronous spectral phase encoding(SPE) optical codedivision multipleaccess(OCDMA) systems, with which the bit error probability of synchronous SPEOCDMA systems was derived. Monte Carlo simulations were used to verify and compare the bit error probabilities of random and synchronous SPEOCDMA systems. The numerical results reveal that the random SPEOCDMA systems can meet the need of high rate alloptical communication, while synchronous ones can not.更多还原
