isodata implementation for matlab

通信中的tcm&16qam体制的研究，matlab源程序代码，采用viterbi应判决译码(Communication tcm & 16qam study of the structure, matlab source code, used to be decision viterbi decoding)

说明：  有关数字通信的matlab实现，进行数字信号处理的matlab仿真(digital signal processing is completed by matalab .including psk bpsk qam module duojingxindao dengdeng )

通过对数据滤波来进行对静态效应的消噪过程，本代码使用了空间滤波、组合滤波、中值滤波等方法进行对比。(Through data filtering to eliminate noise of static effects of the process, the code uses the spatial filtering, a combination of filtering, median filtering and other methods were compared.)

用于三分类的bp算法matlab程序 下面是一个两概念（一个三角形和一个矩形）学习的例子，是一个典型的多分类例子 分类结果的正确率可通过训练网络进一步提高 (for three classification algorithm Matlab procedures bp below is a two concepts (a triangle and a Moment fractal) learning example is a typical example of multi-classification results of the correct classification rate can be further enhanced training network)

可以针对大量数据画图，并可以求出距离，根据距离可以充当权值，进行问题的最短路分析等(For drawing large amounts of data can, and can be obtained from the)

微动经典文献，可以帮助大家学习微动方面的知识。里面包含三篇文献，都是雷达目标回波的。(Fretting classic literature can help us learn fretting area. Which contains three documents are radar target echo.)

说明窗函数为文献窄时，STFT无频域的定位功能；(Note, when a narrow window function of literature, STFT-free frequency domain positioning function )

说明：  在MATLAB里开发的几个常用的图像处理工具，简单易用，初学者可以试试。(matlab image process easy )
