聚类分析技术已经广泛应用于基于内容的图象信息挖掘领域，该技术提高了图象检索的速度和质量。K-均值算法和自适应算法是两个典型的聚类分析算法()

用matlab编写的利用Hough变换法提取直线的代码，用该函数实现利用Hough变换提取直线的功能。(Written by matlab extracted using Hough transform line of code, with the function to achieve the use straight-line Hough transform to extract features.)

This function provides an ARMA spectral estimate which is maximum entropy satisfying correlation constraint (number of poles)and cepstrum constrains (number of ceros)

The code introduces postcoding technique in ofdm system that results in a much less complex mechanism and provide similar result as are obtained with precoded system. In this technique the coding part is done after the ifft block that is initially the data is converted to frequency domain n then coding is introduced.

创建动画 播放动画 分别读入图像 用imshow函数显示(Play the animation to create animated images were read into the display with the imshow function)

gps信号的自相关，以及boc信号的自相关(gps signal autocorrelation, and boc autocorrelation)

说明：  面阵中二维角度DOA估计算法，采用ESPRIT，经典算法，注释清晰，可拿来直接用(Two dimensional angle DOA estimation algorithm in array, using ESPRIT, classic algorithm, clear notes, can be used directly)

TD_SCDMA中的联合检测算法 TD_SCDMA中的联合检测算法 (TD_SCDMA in the joint detection algorithm)

Find indexes neighbors

实现了卷积码（2,1,3）编码以及解码的功能，已验证通过(Achieved (2,1,3) convolutional encoding and decoding functionality code validated by)
