首先要对样本进行聚类分析，以此来确定模糊规则个数。利用K-means法对样本聚类。(First cluster analysis of samples, in order to determine the number of fuzzy rules. Method using K-means clustering of the sample.)

Signal models, echo cancelations adaptive filtering

用matlab实现QPSK调制，各路信号的频谱，高斯白噪声信道(QPSK modulation to achieve with matlab, and the brightest signal of the spectrum, white Gaussian noise channel)

％File: c9_estimatepi.m ％有5个pi的估计，每一个都是基于500次重复随机试验，所得的pi的五个估计值用以下向量表示 ％pi的估计值=[3.0960 3.0720 2.9920 3.1600 3.0480] ％如果对5个结果进平均，则pi的估计值=3.0736,这样的结果等价于2500次的试验结果。( File: c9_estimatepi.m have 5 pi estimates are based on a randomized trial to repeat 500 times the income of the five estimated value of pi with the following vector, said the estimated value of pi = [3.0960 3.0720 2.9920 3.1600 3.0480] if the results into an average of 5, then the estimated value of pi = 3.0736, so the result is equivalent to 2500 times the test results.)
