原理：乘同余法产生随机数来生成均匀分布、瑞利分布、正态分布，压缩包包括3个分布的Matlab源代码(Principle: multiplicative congruential method to generate random numbers to generate uniformly distributed ，Rayleigh distribution and normal distribution.This package includes three distribution of Matlab source code.)

灰色理论的讲解，带有matlab程序实例说明，代码可以直接复制使用(Gray theory to explain, with the matlab program examples, the code can be copied directly use)

完美非均匀质量载荷压电薄膜，这是一个MATLAB程序，可以运行。(Perfect non-uniform mass loading piezoelectric film, which is a MATLAB program that can run.)

说明：  《现代通信系统（mmatlab版）第二版》所有源代码(C ontemporary Communication Systems Using Matlab)

说明：  多基时差雷达定位算法。以雷达测量误差分布规律入手，找到从多个地面时差雷达所测数据中找到较为精确的目标位置。对地面雷达的布站原则也有一定意义。(More than the time difference between the radar-based positioning algorithm. To the radar measurement error distribution to start to find the time difference from several ground-based radar measured data to find a more precise target location. Cloth on the ground radar stations have a certain sense principles.)

说明：  模糊数学中的波达排序，还有模糊聚类分析的MATLAB源代码(Borda sort,Fuzzy Cluster Analysis)

A good code for plotting different clusters with different colors

In this letter, we employ orthogonal random beam-forming (ORBF) for the worst-case multi-user downlink scenario whereeachuseriswiretappedby one eavesdropper. Two oppor-tunistic scheduling techniques that ensure confidentiality by ex-ploiting multi-user diversity are investigated thefirst technique (optimal) requires limited feedback of the effective signal-to-in-terference ratio (SIR) from all the users
