mmse-sic

Anyone can give me some ideas about MMSE-SIC implementation in Matlab. I have already done the MMSE part, the left is SIC part. I wonder what does it mean by "Substract stream from receive vector".
Thanks a lot.
 

mmse sic

I got this principle expression for MMSE receiver is

G=H*(H*H + No/Po I )^-1 *x

Where H -- channel matrix

I --- identity matrix

X --- received vector

Iam not understand about the above expression That is what is No/Po and why multiplying with I etc.. Can you please help me ...

Please help me to clear the above....

iam waiting reply from u...
 

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_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**
