在经典波达角估计方法多重信号分类算法中提出了改进(Angle of arrival estimation method in the classical Multiple Signal Classification algorithm in the proposed improvements)

自由空间光通信系统在大气湍流信道下的3个主要性能指标分析，即平均误码率、中断概率和平均信道容量。其中大气湍流采用gamma-gamma湍流信道衰退模型。3个M文件为平均误码率与平均信噪比之间的关系(BER_SNR.m)，中断概率(OutageP.m)，以及平均信道容量与平均信噪比之间的关系（C_SNR.m）。程序可直接运行。(The analysis of 3 key performance indicators of Free-Space Optical communication system in atmospheric turbulent channel, namely the average bit error rate, outage probability and the average channel capacity. The atmospheric turbulence is modeled by the gamma-gamma turbulent channel fading model. Three M-files are the relationship between the average bit error rate and the the average SNR (BER_SNR.m), outage probability (OutageP.m), the relationship between the average channel capacity and the average SNR (C_SNR.m).The programs can run directly.)

这是一个可执行的向量量化vector编码程序,希望对大家有所帮助(This is an executable vector encoding vector quantization process, I hope all of you to help)

模糊聚类方法，用相关系数法构造模糊相似关系矩阵r，构造了模糊等价评判矩阵，为了方便下载者使用，把代码进行了优化，可直接把矩阵带进去使用。(Fuzzy clustering method, using the correlation coefficient method to construct the fuzzy similarity relation matrix r, construct a fuzzy equivalence evaluation matrix, in order to facilitate the download to use, the code has been optimized, can go directly to the matrix with the use.)

Ising Model is described here in primary manner. The other versions are upcomming..
