function [CAP] = capacity_SU_TDMA_CL_ML(H,SNR,normalize)
|

%
|
|
% [CAP] = capacity_SU_TDMA_ML(H,SNR,normalize)
|
|
%
|
|
% This function calculates the multiuser (MU) capacity of the channel
|
|
% assuming a time-shared single user (SU) MIMO tranmission and a ML receiver.
|
|
% The channel gains are normalized, such that E(|h_{i,j}|^2) = 1 hold for
|
|
% each user. 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
