This is part of DTC-ST strukture work in matlab simulink

matlab课件一共9章，压缩的，需要解压一次。(matlab Courseware)

利用最小二乘法的原理高精度估计正弦波信号的幅值，频率和初相(The principle of using the least squares method estimated sine wave signal amplitude, frequency and initial phase of high-precision)

该文档第一部分总结了matlab中的基本函数其表达式，编程以及范例。第二部分讲了如何插值拟合以及查表。里面有非常详细的解释，并且配有程序范例。(The first part of the document summarizes the basic function of matlab in its expression, programming, and example. The second part of the talk about how to fit and look-up table interpolation. There are very detailed explanation, and with a program example.)

　MUSIC 算法是利用接收数据的协方差矩阵(Rx)分离出信号子空间和噪声子空间，利用信号方向向量与噪声子空间的正交性来构成空间扫描谱，进行全域搜索谱峰，从而实现信号的参数估计。(MUSIC algorithm is used to receive data covariance matrix (Rx) to isolate the signal subspace and noise subspace, using the signal direction vector and noise subspace orthogonality to form the spatial scan spectrum, full-domain search peaks in order to achieve signal The parameter estimation.)

说明：  一种MGA方法(Contourlet变换)程序包，相信对从事基于图像表示理论方面的朋友一定有用！(A kind of MGA method (Contourlet transform) package, I believe in the theory of image-based friends that must be useful!)

matlab环境下，使用双线性插值法实现缩放图像(matlab environment, using a bilinear interpolation method to achieve image zoom)

this simulation is a way for watermarking and steganography with WOW

对于一维波的压缩感知重构算法，使用OMP算法，重构效果良好，供参考 (For the one-dimensional wave of compressed sensing reconstruction algorithm, using OMP algorithm to reconstruct the effect is good, for reference)

合成孔径雷达（SAR)目标成像仿真，用平面波展开法计算二维声子晶体带隙,包括最后计算压缩图像的峰值信噪比和压缩效果的源码。( Synthetic Aperture Radar (SAR) imaging simulation target, Computation Method D phononic bandgap plane wave, Including the final calculation of the compressed image peak signal to noise ratio and compression of the source.)
