在DS-spread spectrum系统中,噪声为加性高斯白噪声,传统单用户检测,线性解相关多用户检测和最小均方误差多用户检测的性能比较-In the DS-SPREAD specturm, noise is always white Gauss noise.

采用最小均方准则误差的自适应滤波器，根据输入信号的统计特性自动调整其结构参数，以满足某种最佳准则的要求。-Guidelines for use of minimum mean-square error of the adaptive filter, according to statistical characteristics of the input signal automatically adjusting its structural parameters, in order to m

多天线系统的各种信号检测算法包括迫零，最小均方误差，最大似然，改进的最大似然等-A variety of multi-antenna systems signal detection algorithm, including zero-forcing, minimum mean square error, maximum likelihood, the improved maximum likelihood, etc.

以下是均方误差、峰值信噪比以及熵的程序代码在MATLAB 中的实现-The following is the realization of the mean square error, peak signal to noise ratio and entropy code in MATLAB
