说明：  噪声中非平稳信号的频谱分析，基于MATLAB，实验报告一份(Nonstationary noise frequency spectrum analysis, based on MATLAB, a lab report)

基于MATLAB的jPEG压缩程序，很实用！(matlab，jpeg compression)

是关于空时编码的nrs ，给出了Matlab程序实现，希望有借鉴意义。 (on space-time coding nrs given Matlab program, with the hope of reference.)

采用matlab中的函数对图像进行放大缩小，缩小到原来的0.2倍，再放大到原来大小(Using matlab function image zoom, narrowed to 0.2 times, and then zoom to the original size)

能够屏蔽文件中一些禁用语，能够设置某些语言(Be able to document some of mask to disable language, be able to set some languages)

采用matlab设计数字滤波器的源程序，包含滑动滤波器、切比雪夫低通、带通滤波器等！ (Digital filter design using matlab source, including sliding filters, Chebyshev low pass, band pass filter!)

MUSIC算法[1]是一种基于矩阵特征空间分解的方法。从几何角度讲，信号处理的观测空间可以分解为信号子空间和噪声子空间，显然这两个空间是正交的。信号子空间由阵列接收到的数据协方差矩阵中与信号对应的特征向量组成，噪声子空间则由协方差矩阵中所有最小特征值（噪声方差）对应的特征向量组成。(MUSIC algorithm [1] is a feature space based on matrix decomposition method. From the geometric point of view, the signal processing can be decomposed observation space the signal subspace and the noise subspace, it is clear that the two spaces are orthogonal. Signal Subspace data received by the array covariance matrix and eigenvectors corresponding to the signal component, the noise subspace from the covariance matrix of all the smallest eigenvalue (noise variance) eigenvector components.)
