Cyclic Spectral Correlation

这是m序列的matlab调制和解调程序，值得一看哦(This is the Matlab m-sequence modulation and demodulation process, an eye-catcher oh)

单脉冲雷达测速测距的matlab程序，仿真图是速度、距离、幅度三维图像(Speed ​ ​ and distance measurement in Single-pulse radar)

Spread spectrum merupakan sistem dimana sinyal yang dikirimkan memiliki bandwidth yang jauh lebih lebar daripada bandwidth sinyal informasinya sendiri. Proses pelebaran bandwidth sinyal informasi ini dilakukan pada sisi pengirim dan disebut spreading. Sebaliknya, proses penyempitan kembali bandwidth sinyal informasi dilakukan di sisi penerima, dan disebut despreading. Pada gambar 1 berikut menunjukkan proses yang terjadi pada sistem spread spectrum.

Matlab中用GUI设计一简单计算器。(err)

说明：  采用matlab语言编写的最小二乘算法程序，需要的请下载(Matlab languages using least-squares algorithm procedures needed please download)

里面搜集了各种用matlab编写的回归分析算法，相信对参加建模竞赛的同学们会有所帮助。(Which collected a variety of regression analysis using algorithms written in matlab, I believe the students who participate in modeling contest will help.)

Decompose image into subbands (undecimated wavelet), denoise, and recompose again. fh = decomp_reconst_wavelet(im,Nsc,daub_order,block,noise,parent,covariance,optim,sig) im : image Nsc: Number of scales daub_order: Order of the daubechie fucntion used (must be even). block: size of neighborhood within each undecimated subband. noise: image having the same autocorrelation as the noise (e.g., a delta, for white noise) parent: are we including the coefficient at the central location at the next coarser scale? covariance: are we considering covariance or just variance? optim: for choosing between BLS-GSM (optim = 1) and MAP-GSM (optim = 0) sig: standard deviation (scalar for uniform noise or matrix for spatially varying noise) Javier Portilla, Univ. de Granada, 3/03 Revised: 11/04

这是一个MATLAB的MUSIC（multiple signal classification）算法，用来算DOA（到达方向角）(This is a MATLAB-MUSIC (multiple signal classification) algorithm is used to count DOA (direction of arrival angle))

利用harris算法进行角点检测，然后利用鼠标将角点的坐标读取出来，存到数组当中(harris corner detection)

一个用matlab编写的用于故障诊断的源程序，可用于故障的简单诊断，工学习和参考用。(a prepared using Matlab for fault diagnosis of the source can be used in a simple fault diagnosis, work study and reference.)
