Throughput analysis of opportunistic feedback for downlink multiuser diversity with capture effect

Journal Article


Abstract


  • An opportunistic feedback protocol has been proposed

    in the literature to achieve multiuser diversity for the

    downlink transmission of a multiuser wireless system. In this

    letter, through theoretical analysis and extensive simulations, it

    is shown that the capture effect can have a significant impact

    on system throughput. It is also shown that, to achieve optimal

    throughput, the number of minislots used for opportunistically

    finding a user in the protocol should not be too large due to the

    overhead induced by the control packets.
