对时变信道下差分放大-前向中继的选择性合并性能的研究，这是IEEE Transactions on Wireless Communications, 2014 一篇文章的对应仿真，是作者本人写的程序(Description simulation of the following paper: M. R. Avendi and Ha H. Nguyen, Performance of Selection Combining for Differential Amplify-and- Forward Relaying Over Time-Varying Channels, IEEE Transactions on Wireless Communications, 2014 Required Products MATLAB MATLAB release MATLAB 7.13 (R2011b) )

说明：  本程序用于完成BPSK、QPSK、pi/4QPSK、OQPSK、8PSK、16QAM、32QAM、64QAM和128QAM的调制仿真。并可任意扩展到MPSK和MQAM。程序分成四个部分，fir.m对基带码元序列进行脉冲成型，可选矩形脉冲，升余弦脉冲和平方根升余弦脉冲； modal.m 为主程序，完成岁各种信号的基带星座图映射、脉冲成型和调制；pi4QPSK.m 为pi/4QPSK信号的星座图映射程序；test1.m给出一个简单的频谱显示测试。(This procedure for the completion of BPSK, QPSK, pi/4QPSK, OQPSK, 8PSK, 16QAM, 32QAM, 64QAM and the modulation 128QAM simulation. Arbitrary and may be extended to MPSK and MQAM. Procedures are divided into four parts, fir.m of baseband symbol pulse sequences forming, optional rectangular pulse, raised cosine square root raised cosine pulse and pulse modal.m-based procedures, the completion of the age range of the base-band signal constellation diagram mapping, pulse shaping and modulation pi4QPSK.m for pi/4QPSK signal constellation diagram mapping procedures test1.m given spectrum shows a simple test.)

利用MATLAB语言编写的腐蚀模拟程序，可以用于MATLAB软件的腐蚀计算(The corrosion simulation program written by MATLAB language can be used to calculate the corrosion of MATLAB software.)

The model of a discrete system with variable step size calculation is given in the file vsfunc.m. Considered S-function simulates the signal delay device. The delay time is determined by the input signal.

Beamforming using Leas Mean Square

说明：  这是matlab的根轨迹程序代码，很好很好的代码(This is the root locus matlab code, very good very good code)

对64QAM单载波通信系统进行仿真，内附实验报告，可绘制星座图(Simulation of Digital communication system by matlab)

说明：  用matlab中的FFT函数实现了正弦信号，矩形信号，和白噪声的频谱分析(FFT with matlab function in a sinusoidal signal, the rectangular signal, and white noise spectrum analysis)
