这是清华大学出版社胡广书著的《现代信号处理》的Matlab源程序 (This is widely Hu Qinghua University Press book with the "modern signal processing," the source Matlab)

通过比较传统仅移相的波束与移相+理想延时的波束，来说明述S波段宽带阵列孔径渡越现象(To demonstrate the aperture effct of S_band windband array, this programe comparing the beam pattern of the traditional beamforming method "phase shifting only" with that of "phase shifting+ ideal delay".)

This is some code for reading hyperspectral images aviris format to matlab

本程序是针对UCI图像数据集上的图像进行重构与识别的实验(This procedure is for the UCI data sets on the image to reconstruct the image and recognition of the experiment)

给出了理想光具组系统矩阵的MATLAB计算程序，并借助MATLAB进行光线追迹与数值拟合，得到了像差(球差)的多项式及曲线图．(Elastic viscoelastic correspondence principle is a method which is used to solve viscoelastic problems with elastic results using inverse Laplace transformation．The principle can combine elastic and viscoelastic me— chanies together．Therefore traditional mechanics of materials is qreatly enriched because of introducing the new materials and new theory．)

维纳滤波法语音增强，为函数文件，需要另外一个脚本调用，形参格式参照文件第一行。(Wiener filtering speech enhancement, as a function of the file, you need to call another script, parameter format, refer to file the first line.)

Direct sequence spread spectrum (DSSS) communication systems has been widely used in these years for its advantage of wide spectrum, low working Signal-to-Noise ratio (SNR), anti-interference, anti-multipath effect and capability of LPI and LPD. They are increasingly replacing conventional communication forms and obtaining extensively applications in modern military and commercial communication systems, for example, CDMA communication system, GPS , measuring and control system, satellite chain, identification of friend or foe and etc. Therefore, corresponding DSSS electronic counter technique becomes a big problem to solve in electronic warfare domain. DSSS electronic counter technique including blind detection, blind parameter estimation and spreading sequences estimation. For the issue of DSSS electronic counter technique of DSSS/QPSK signal damaged by strong additive white Gaussian noise (AWGN), the main research content in this dissertation as follow.
