For simplifying the discussion, we will assume that there is no pulse shaping at the transmitter. In a multi-cell massive MIMO system with L cells, the BS with (M) antennas communicates with active mobile users K in each cell. This example uses the filter function to compute averages along a vector of data. HEllo, I am really in trouble please help me I need to make in matlab a 2x2 MIMO system with STBC which will show the BER and the capacity comparing to theoritical values of a MRC 1x2 and MIMO 2x1or whatever i could add, it would be good according to my supervisor Anyone who could help? pleeeeeeeease help I would really thank you. Description: MATLAB realizes the comparison of three algorithms in MIMO, ML, MSE and ZF.
