MU-MIMO Simulation

    Hi, everyone
    I had trouble simulating MU-MIMO. I have followed the requirement in the roundRobinSchedulerMU.m and added the text block into “+feedback_calculation.CLSM_PMI_feedback.m.”
    Also, I change the simulation configuration

    simSet = [5 4 2]; % tx_mode=5, nTx=4, nRx=2
    LTE_config.bandwidth  = 1.4e6;
    LTE_config.scheduler  = 'round robin MU';
    LTE_config.trace_version = 'v2';

    However, simulator shows errors about “Inner matrix dimensions must agree.” in network_elements.UE/calculate_per_layer_interference_power. How do I change the simulation(configuration) setting to simulate MU-MIMO successfully?
    Thank you.
    Note: My version of Vienna SL simulator is v1.8r1375.


    Dear Yang,

    we did not debug the code for MU MIMO properly, sorry for the inconvenience.
    Please use the command “dbstop if error” before starting the simulation. Then, after the crash, try to figure out, which matrix dimensions are not matching.

    Best regards,
