matlab源码关于模糊K均值聚类算法，很好的，适合大家下载研究学习(matlab source code on the fuzzy K-means clustering algorithm, very good for everyone to download research study)

该程序主要说明直扩系统抑制正弦干扰方面的有效性。绘出不同幅度的正弦干扰信号及无干扰时的误码率.( This procedure mainly showed that expands the system to suppress the sine disturbance aspect straight the validity. Draws the different scope the sine unwanted signal and does not have when the disturbance error rate. )

常规波束形成，均匀加权，给个权重因子，线列阵常规波束形成。(Conventional beamforming, uniform weighting, to a weight factor, the conventional line array beamforming.)

霍夫曼编码的具体方法：先按出现的概率大小排队，把两个最小的概率相加，作为新的概率 和剩余的概率重新排队，再把最小的两个概率相加，再重新排队，直到最后变成1。每次相 加时都将“0”和“1”赋与相加的两个概率，读出时由该符号开始一直走到最后的“1”， 将路线上所遇到的“0”和“1”按最低位到最高位的顺序排好，就是该符号的霍夫曼编码。(Specific methods Huffman coding: the probability of emergence of the size press line, the two smallest sum probability, as a new probability and the probability of re-queue the remaining, then the minimum of two probabilities are added, and then re-queue, until finally become one. Each time the sum will be 0 and 1 Fu added two probabilities, when read by the symbol has come to begin the final 1 , the route will encounter a 0 and 1 at the lowest to the highest bit of the right order, that is the symbol of the Huffman coding.)
