Abstract

This paper concerns a simple limited feedback scheme taking temporal correlation into account during the feedback design in slow fading environment. In this method, the transmitter and the receiver reuse the past channel state information (CSI) as side information. Feedback, that is designed to leverage the side information, is sent from the receiver to the transmitter using a predetermined update period. The feedback update period is determined by characterizing the temporal correlation statistic, so that the proposed feedback reuse scheme outperforms a feedback scheme that does not adapt to the temporal correlation. To measure the performance, average effective SNR loss is used. Bounds on the feedback update period and the amount of feedback needed are derived. Simulation results show a reduction in the required average feedback overhead and a performance improvement when comparing the proposed scheme with prior feedback approaches.
