摘要
为了解决三分支信号检测(TBSD)方案的上界表达式不精确的问题,提出了一种频谱-振幅编码光码分多址(SAC-OCDMA)系统TBSD方案,建立了一个严谨的数学模型,并对该方案进行了数值评估和仿真。仿真结果表明,该方案在传输速率为500 Mb/s、1 Gb/s时能够完全消除多用户干扰(MUI),而在传输速率为5 Gb/s时则可以消除大部分MUI,证明了数学模型的精确性。
To solve the problem of imprecise upper bound expression of three-branch signal detection(TBSD)scheme,a TBSD scheme of spectrum-amplitude coded optical code division multiple access(SAC-OCDMA)system is proposed,a rigorous mathematical model is established,and the scheme is numerically evaluated and simulated.The simulation results show that the scheme can completely eliminate multi-user interference(MUI)at the transmission rate of 500 Mb/s and 1 Gb/s,and most MUI can be eliminated at the transmission rate of 5 Gb/s,which proves the accuracy of the mathematical model.
