产生随机信号观测样本，不同信噪比和归一化频率。利用基于FFT的自相关函数快速计算方法估计其自相关函数。(Generate random signal observation samples, different signal to noise ratio and normalized frequency.Based on FFT calculation method of the autocorrelation function to quickly estimate the autocorrelation function.)

QPSK的matlab仿真，希望对大家有所帮助(QPSK in matlab simulation, we want to help)

说明：  最优多用户检测，即最大后验概率的算法，主要是用于多用户检测中(Optimal multi-user detection, that is, maximum a posteriori probability algorithm, mainly used for multi-user detection)

求小波系数的程序，即快速有简单 (wavelet coefficients for the procedure, Quick is a simple !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! )

计算信噪比，计算公式是信号能量比上噪声能量(SNR Calculation，signal power divide noise power)

A UMAT Coding for Kinematic Hardening Plasticity.

简单的单位转换系统，用matlab进行实现，直接在matlab下运行(Simple unit conversion system using matlab to achieve a direct run in matlab)

在matlab上的FDTD程序关于一维时域有限差分(Matlab program on the one-dimensional FDTD finite difference time domain)
