kmeans

程序的主要功能是做了一定范围的信噪比下，对每个信噪比：随机信号QPSK调制； 根据Alamouti方案的矩阵进行编码；发送信号经过瑞利信道和加入高斯白噪声； 接收信号采用最大比合并的方法；最后对合并信号进行最大似然判决并求误符号率。 结果表明10^-3对应大约12->13dB(Procedure main function is to do a certain range of SNR for each signal to noise ratio: random signal QPSK modulation program in accordance with Alamouti coding matrix send signals through Rayleigh channel and adding Gaussian white noise received signal using maximal-ratio combining method Finally the combined signal and the maximum likelihood decision for symbol error rate. The results showed that about 10 ^-3 corresponds to 12-> 13dB)

关于matlab的图像处理的7个源代码，均自己编写并已经应用到已经开发的软件中，如有其他相关功能代码的需要，可联系本人(Matlab image processing on the 7 source code, all I have written and have been applied to the software have been developed in other related functional code if necessary, contact me)

这个是芬兰人写的《WCDMA无线网络规划与优化》书上对应的Matlab源代码。这本书很经典。(this is the Finns write "WCDMA Wireless Network Planning and Optimization" book on the corresponding source Matlab code. This book classic.)

遗传算法matlab代码，很不错，值得看看(Genetic algorithm matlab code, very good, worth a look)

S 变换是 Stockwell（1996）等提出的一个时-频分析方法，它结合了短时 Fourier 变换和小波变换的特点，能够完全无损地实现逆变换。(S-transform is a time-frequency analysis method proposed by Stockwell (1996). It combines the characteristics of short-time Fourier transform and wavelet transform, and can realize inverse transform completely without loss.)

排列熵与多尺度排列熵计算，源于matlab exchange(used for calculating permutation entropy and multiscale PE，which is from Matlab file exchange)
