ESPRIT算法是一种用于信号到来角(DOA)估计的直接求解方法,本程序中含有3种不同的算法均为自编(ESPRIT algorithm is used to signal the arrival angle (DOA) estimation of the direct methods, its performance at low signal to noise ratio (SNR) and signal correlation will seriously undermine)

详细描述和matlab在图像处理方面的应用，书中附有代码可供参考。(Detailed descriptions and matlab in image processing applications, the book with the code for reference.)

This file is lateral vehicle velocity observer which was verified via Carsim software and matlab/simulink.

分布式压缩感知中的SOMP算法，可以用于实现JSM-2的场景的信号的重构(The SOMP Distributed compressed sensing algorithm can be used to implement the JSM-2 signal of the reconstructed scene)

this is programm for propagation that can help you to solve the case in propagation and transmission media fron transmitter to receiver. we can count link budget in propagation.

hybrid of ICA and K-mean to improve K-mean

读入指定的音频序列，并对其进行无损预测编码和DM调制编码(Read into the specified audio sequences, and its lossless predictive coding and modulation coding DM)

说明：  基于MATLAB的有源滤波器的实现，很简单，能看懂。(The realization of active filter based on MATLAB is simple and understandable.)

该算法是经典的信噪比估计算法——误差矢量幅值法，通过计算接收信号中同相分量和正交分量的二、四阶矩，该算法能够很好的估计信号的信噪比(The algorithm is a classic signal to noise ratio estimation algorithm- the error vector magnitude method, by calculating the received signal with the phase component and quadrature component of the second, fourth-order moment, the algorithm can estimate a very good signal to noise ratio)

基于星座图的QPSK调制解调程序，功能函数，可以直接调用进行QPSK调制解调(Based on a constellation of QPSK modulation and demodulation process, the performance function can be called directly conduct QPSK modulation and demodulation)
