运用差分进化算法实现一维线阵方向图优化，还包含了带有单纯形算法局部搜索的混合算法程序(One-dimensional linear array pattern optimization using differential evolution algorithm)

matlab仿真模型，空间矢量控制模型，可以当作毕业设计内容使用。(matlab simulation model, space vector control model can be used as a graduation project content.)

EMpht is a programme for tting phasetype distributions􀀀 It can be used either to t a phasetype distribution to a sample which may contain censored observations or to make a phase-type approximation of another continuous distribution􀀀 The fitting procedure consists of an iterative estimation of the parameters of the phasetype distribution

QPSK调制后产生QPSK信号，QPSK信号分别通过AWGN信道、Rayleigh衰减信道和Rician衰减信道，分别通过QPSK解调出数字信号，通过输入与输出数字信号的对比计算出仿真过程中的传输误比率，并将其与各衰减信道的理论误比率进行对比(Generate QPSK signal QPSK modulation, QPSK signals through AWGN channel, Rayleigh fading channel and Rician fading channel, respectively, through the QPSK demodulation of digital signals by comparing input and output digital signals to calculate the simulation process of transmission error rate, and to compare with the theoretical error rate for each decay channel)
