基于普通最小二乘法的ARMA模型谐波频率估计 (Ordinary least squares method based on the ARMA model of harmonic frequency estimation)

OFDM simulaion MATLAB code

一种非常有效的用于运动模糊图像恢复的Matlab算法。保证好用，并且有pdf说明，有做图像去迷糊的同学可以看看。(An extremely effective Matlab algorithm for recovering image motion blur.)

the simulation provides computation of target reflectivity data in the deficient elevation domain. Simulations are implemented to test the decoupled least-squares technique for high resolutionspectral estimation of target reflectivity.all seven (7)files should be downloaded for the simulation to work.(dls3D.m,estimate.m,get2S1Data.m,getConstraints.m, getImageData.m,getPixelData.m, getSLICYData.m)

这个是一个很好的程序，里面的参数可以修改一下(This is a very good program, which you can modify the parameters)

说明：  bpsk仿真中间有两个方面的内容，很好的仿真软件(There are two files in the zip folder. bpsk_spread.m and jakesmodel.m Steps for simulation: 1] Run jakesmodel.m first 2] Then run bpsk_spread.m . 3] Note that during the first run bpsk_spread.m has no rayleigh fading.This is because the corresponding code has been commented 4] The resulting performance is stored in BER_awgn. 5] Now uncomment the Rayleigh Fading code in bpsk_spread.m file. 6] Same time comment BER_awgn (line 112) and uncomment BER_ray variable. 7] Run the simulation. )

数字调制技术的发展日新月异现如今信息技术不断的推陈出新，信息的传输及通信起着支撑作用。而对于信息的传输，数字通信已经成为重要的手段。因此，数字信号的调制就显得非常重要。数字调制是通信系统中最为重要的环节之一，而实现数字调制需要的方法就需要用键控法来实现，比如可以对载波的振幅、频率和相位进行键控。(ASK , FSK , PSK modulation and demodulation of the simulation comparison )
