以ofdm作为调制方式的发送端的信道模型(To ofdm transmitter as modulation of the channel model)

对二进制序列进行DPSK调制，绘出绝对码、相对码、调制后的曲线、加噪声后的曲线图(Sequence of binary DPSK modulation, draw absolute code, the relative code, modulated curve, after curve plus noise)

一本关于matlab的好书，是一本教程，请欣赏学习。(one of the best books on Matlab is a guide, please appreciate learning.)

harris角点检测的小程序，希望对大家有用，谢谢(harris corner detection of small procedures, we hope to be useful, thank you)

说明：  基于三对角矩阵LU分解的追赶法，编写的追赶法分解五对角矩阵，并在此基础上解以五对角为系数矩阵的线性方程组。(Tridiagonal matrix based on LU decomposition method to catch up, catch up with the preparation of the Decomposition of five pairs of diagonal matrix, and on this basis for the solution to five diagonal coefficient matrix of linear equations.)

Time-Frequency Training OFDM with High

Recurrence quantification analysis (RQA) of recurrence plots (RPs)

这段代码是基于pca方法的数字图像处理技术，具有实际用应价值(This code is based on the method pca digital image processing technology, with the actual values used should be)

说明：  描述了采用卷积码的QPSK系统的代码编写，通过运行代码可以看到系统性能(bpsk)

This is demo program about electronic voting. This base on elgamal agorythm. It can work well in Matlab 2012.
