Abstract


  • An opportunistic feedback protocol with maximum

    throughput (MT) scheduling has been proposed in the literature

    to achieve multiuser diversity for the downlink transmission of a

    wireless system, and its system capacity has been analyzed with

    the assumption that the received signal-to-noise ratios (SNRs)

    for the users are independent and identically distributed. In this

    paper, fairness and capacity performances of the opportunistic

    feedback protocol are analyzed for SNRs with independent but

    not necessarily identical distributions. In addition to MT scheduling,

    we also analyze the fairness and capacity performances for

    proportional fair (PF) scheduling. Compared with MT scheduling,

    numerical results demonstrate that the PF scheduling achieves

    strict fairness at the cost of about 10% system capacity loss over

    Rayleigh fading channels. Moreover, the feedback threshold and

    random access probability of the opportunistic feedback protocol

    are jointly optimized using a constrained gradient descent method

    to maximize system capacity.
