    Hello,

    I’m new on 5G Link Level Simulator. On main.m at Line 14 I selected simulationScenario = ‘NOMA’. But program gave error as:

    Error using ChannelEstimation.PilotSymbolAidedChannelEstimation (line 99)
    Too many input arguments.

    
    Error in Elements.Link/updateLink (line 114)
                        ChannelEstimator = ChannelEstimation.PilotSymbolAidedChannelEstimation( ...
    
    Error in main (line 44)
    parfor iSweep = 1:length(simParams.simulation.sweepValue) % this may be 'for' or 'parfor'
    Caused by:
        Error using repmat
        Too many input arguments.

    I have MATLAB R2013a. How could I overcome of this problem?

    Would you give me avices please?

    Best Regards…

    Hi,

    sorry for my late response.

    Do you have Matlab’s parallel computing toolbox? If this is not the case, please change “parfor” in line 44 of main.m to a simple “for”. Even if you have the toolbox, this is beneficial for debugging.

    Hello,

    I’m new on 5G Link Level Simulator I have version 1.2 and MATLAB R2018b. On main.m at Line 14 I selected simulationScenario = ‘NOMA’.when change codebook from LTE TO 5G
    scStr.simulation.codebook = ‘5G’;
    But program gave error as:

    Error using Parameters.SimulationParameters/initializeLinks (line 1672)
    The configuration for the number of horizontal and vertical antennas does not fit the total number of antennas.

    Error in main (line 60)
    Links = simParams.initializeLinks(Links, BS, UE); %#ok
    Would you give me advices please?

    Best regards

    Dear Roaa,

    The error message you got indicates that the total number of antennas simulation.nAntennasBaseStation and the antenna configuration simulation.antennaConfiguration do not fit. For the 5G codebook, the total number of antenna has to be equal to 2*N_1*N_2.

    Best,
    Mariam
