精通matlab6.5 (北航 张志涌),绝对的好书(Proficient matlab6.5 (BUAA Zhang Yong), the absolute good)

ofdm发送端和接收端，根据短训练字的特性进行相关运算，进行信号到达检测，当检测到相关值大于门限一定次数后，认为有信号到达。(ofdm sending end and receiving end, according to the characteristics of the short training word correlation operation, the signal reaching the detector, when the detected correlation value is greater than the threshold after a certain number of times that a signal arrives.)

数据矩阵运用非负矩阵分解算法，分解得到两个低维矩阵，并用于信号分离。(The data matrix is decomposed into two low-dimensional matrices by non-negative matrix decomposition algorithm and used for signal separation.)

PLL matlab simulation

该程序描述的是数字电视地面广播中卷积交织部分.因为是卷积交织所以最后结果中出现为的数值表示该值是前一包缓冲数据的数.但针对第一包数据做卷积交织时,这些零位置上最后确实自动补零.(The procedure is described in digital TV terrestrial broadcasting in parts of Convolutional Interleaver. Convolutional Interleaver because it is so final results for the numerical value is that the previous data on the number of packet buffer. But for the first packet data do Convolutional Interleaver These zero position is indeed the last automatic zero.)

VQ的简介与应用说明，并介绍如何在MATLAB中进行仿真应用，值得学习(The introduction and application of VQ, and introduces how to carry on the simulation in MATLAB application, worth learning)

抛物线拟合算法实现代码，已经通过测试可指直接运行(Parabola fitting algorithm code, has passed the tests can be run directly refers to)

说明：  matlab编程的中文版，非常珍贵的电子书！(Chinese version of matlab programming, e-books are very precious!)

Matlab 多小波变换SPHIT编码的图像压缩技术(Matlab based multiwavelet transform SPHIT coding image conpress)
