The avaraging is done over all snapshots and all frequencies. % % PARAMETERS % - H is the input channel (NRx,NTx,Nfreq,NFrames,NUser) % - SNR is the considered SNR (Linear) % - normalize is a flag that indicates if the channel should be normalized % % RETURNS % - CAP is the capacity values % Authors: florian.kaltenberger@eurecom.fr % Copyright: Eurecom Sophia Antipolis % Created: 17/10/2007 % Modified last: 12/12/2007 by florian.kaltenberger@eurecom.fr [NRx,NTx,NFreq,Nframes,NUser] = size(H); if nargin<3 normalize = 1; end CAP_SU = zeros(NUser,Nframes*NFreq); for k=1:NUser CAP_SU(k,:) = capacity_SU_ML(H(:,:,:,:,k),SNR,normalize); end %CAP = mean(CAP_SU,2); CAP = CAP_SU(:);
