用MATLAB编程实现半导体光放大器（SOA）的ASE噪声特性分析，可以计算半导体光放大器的载流子密度，ASE增益，噪声指数，主要用的是半波逼近法来实现数值算法。-Programming with MATLAB semiconductor optical amplifier (SOA) of the ASE noise characteristics analysis, semiconductor optical amplifiers can calculate the carrier dens

在光纤通讯仿真中，产生QPSK，16QAM，64QAM信号，并添加激光相位噪声和自发辐射噪声(In optical fiber communication simulation, QPSK, 16QAM, 64QAM signals are generated, and laser phase noise and spontaneous radiation noise are added.)
