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.
