    Dear moderators,

    In TR36873_Fading_3D_Channel,

    portwise_channel_coefficients(:,1,uu,tt-current_TTI+1,kk) = sum((rearranged_element_channel_coefficent(:,:,tt-current_TTI+1,1,kk).*element_weight),2);

    I do not know why sum the calculated channels per column.
    Do you have any related documents?

    Best regards,
    Kim

    Dear Kim,

    The sum is calculated per column because in our antenna array model we map one column of antenna elements to one antenna port. At this point the channel matrix is saved per antenna port and the vertical dimension of the antenna array is eleminated by this sum.

    For more details, please reffer to the paper: http://jwcn.eurasipjournals.springeropen.com/articles/10.1186/s13638-016-0549-9

    However it is possible to apply different types of antenna element-to-port mappings. The simulator is flexible to implement such schemes.

    Best regards,
    Fjolla
