Re: ofdm

this is my mmse code,could some how help me?it doesn't work.

i have my pdp and its length is L.

SNR = 1/(noiseVar);
beta=1;
power_delay_profile=[power_delay_profile zeros(1,fftlen-(L))];
power_delay_profile=fft(power_delay_profile);
power_delay_profile=diag(power_delay_profile(carriers));

% Calculate frequency correlation matrix
R_hh =power_delay_profile;
R_hy = R_hh + (((beta/SNR)* eye(length(carriers))));
% Calculate LMMSE estimate
h_LMMSE = (R_hh*inv(R_hy)) * h_LS;



please help!

this is the paper i refer **broken link removed**
