Abstract

In frequency division duplex (FDD) wireless MIMO communications, the channel state information (CSI) of the forward link needs to be fed back to the transmitter for precoder design. In practice, the inevitable CSI feedback delay results in system performance degradation. In this paper, to mitigate the CSI feedback delay, an efficient adaptive double codebook based CSI prediction scheme is proposed by exploiting the LTE Release 10 double codebook framework. Simulation results demonstrate that the proposed scheme is effective in mitigating the CSI feedback delay in single- and multi-user (SU/MU) MIMO-OFDM systems.
