Matlab code for Galois field

matlab应用指南，讨论如何用多源代码文件来构造一个程序。(matlab guide, discuss how to use multiple source code files to construct a program)

This is code for Haralick feature extraction for image in matlab. The basis for these features is the gray-level co-occurrence matrix. This matrix is square with dimension Ng, where Ng is the number of gray levels in the image. Element [i,j] of the matrix is generated by counting the number of times a pixel with value i is adjacent to a pixel with value j and then dividing the entire matrix by the total number of such comparisons made.

秩和检验的Matlab源码程序，计算两类变量所含显著差异的变量(Rank sum test of the Matlab source code program to calculate two types of variables contained in significant differences in the variables)

采用SMI算法的零陷波束形成器，有详细的注解，可更改参数(SMI algorithm using Null Beamformer, detailed comments, can change the parameters)

语音信号的盲分离，是一个很好的在没有先验知识的情况下的分离程序！(voice signals in the blind separation is a good in the absence of a priori knowledge of the separation procedure!)

支持向量机比较好的一个例子，包含了参数寻优，训练值回归和测试集的检验，以及方差分析(A support vector machine good example, contains a parameter optimization, training and test sets Regression testing, and analysis of variance)

高级谱分析，作为非线性处理信号，图像直观，方便的特点(Higher order spectrum)

提出了一个采用(2,1,7)卷积码+QPSK的中频调制解调方案,并在Xilinx公司的100万 门FPGA芯片上实现了该系统。该系统在信噪比SNR为6dB左右时可实现速率超过1Mbit/s、误码率 小于10-5的数据传输。 (Proposed a use of (2,1,7) convolutional code+ QPSK modulation and demodulation of the IF program, and in Xilinx' s FPGA chip one million on implementation of the system. The system SNR to 6dB signal to noise ratio at about the rate may achieve more than 1Mbit/s, less than 10-5 bit error rate of data transmission.)
