    Hi,
    I wonder that what is the difference between obj.UE_specific(uu).BLER and obj.UE_specific(uu).BLER_overall in simulationResults.m .

    one more thing is that in squeeze(sum(sum(obj.UE_specific(uu).FER_coded,1),3) ./ sum(sum(obj.UE_specific(uu).used_codewords,1),3)); what is the meaning of “3”?

    best,
    Howdy

    Dear Kim,

    obj.UE_specific(uu).BLER contains the average BLER of each codeword separately (in case of MIMO with multiple data streams), whereas BLER_overall provides the average BLER over both codewords.

    The third dimension of obj.UE_specific(uu).FER_coded represents the spatial dimension; that is, this is the sum over spatial streams (again in caso of MIMO with multiple data streams).

    Best,
    Stefan.
