Matlab coding for mimo ofdm channel estimation

hi everybody.. am doing a project on MIMO OFDM. for that i need MATLAB coding for semi-blind method sparse channel estimation for calculating SNR vs MSE.
PLZ help me

I think u ment MSE vs. SNR..
and where exactly do u have difficulties?

I want to know about the semi-blind method...how to include that in coding..does it has any equation or something....

I am not sure but I think semi-blind means you have to use some training as well as channel statistics in order to retrieve the signal at the receiver.
