monte carlo simulation to demonstrate the performance of Coordinated beamforming.

Hi, I am doing project on "coordinated beamforming based on SVD for multi user MIMO systems with limited feedforward". In the paper, under simulation results they mentioned monte carlo simulation results are used to demonstrate the performance of CBF. The first Subsection demonstrates it's performance in terms of average BER. How to show this? How to get graph for this? I tried BER tool and monte carlo in that but my code is not getting executed. How can i get BER graph for my paper? please help me out.
