hi friends,i am doing my master thesis on LTE.i am trying to implement mmse and
svd estimation but i have some probleme
this is my mmse code,could some onw help me?
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_profilet(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
