BER performance of LSE and sparse channel estimation for OFDM system.

| Watch this File

File Information
Description

In this code, the BER performance of a system which uses sparse channel estimation is compared with a system which uses LSE channel estimation. It is shown that using sparse technique improves the performance of the system

In order to run this code you have to install the cvx from the following web page :
http://www.stanford.edu/~boyd/software.html
cvx is a tool for convex optimization problems. To install the cvx simply download it and save the unzip folder in the MATLAB working directory, and from the unzip folder run cvx_setup.m. Then, you can run this mfile.

Required Products Communications System Toolbox
MATLAB release MATLAB 7.11 (R2010b)
Other requirements CVX communications system toolbox

hello sir,
I have some questions for your code.
Firstly,the Modulation order ofdm.M=4,but the function biterr requires the number of bits.In other words,it should be 2.So I think the argument for the function biterr should use 2 rather than ofdm.M=4.

hello sir,
could you guide line me ,what should i do for ofdm channel estimation using filter bank and also dct instead of fft. i just starting my work but still not on right track.m also searching estimation using compressive sensing,m also download cvx tool but yet not working..

I have learned a lot frome your file. Adding more flexibility to the channel generation will make your code perfect.
