  • This paper considers the Multiple-input-
    multiple-output (MIMO) systems with periodic feedback
    under the assumption that the channel state remains quasi-
    static within a fading block and varies from one block to the
    next based on Markov random process. It is assumed that
    the Channel state information (CSI) is perfectly known at
    the receiver and fed back to the transmitter once every
    period. Given the feedback-capacity constraint in terms of
    maximum number of feedback bits per block, the relation-
    ship between the outage capacity and the feedback rate
    is analyzed. The analysis shows that the outage capacity
    is a non-monotonic convex function of the feedback rate
    and there exists the maximum value of the outage capac-
    ity. Then, to maximize the outage capacity, the optimal
    feedback rates are given by numerical results.
