Distributed MIMO that employs multiple antennas keeps the advantages of the distributed antenna system and the point-to-point MIMO system.A simple feedback that only indicates the capacity autocorrelation information(CAI) can be used in the TDD mode of the distributed MIMO system to decrease the system complexity.To obtain the CAI,this paper examines the channel capacity autocorrelation characteristics of the distributed MIMO system in Doppler spread channel and shows that the capacity autocorrelation coefficient can be predicted by the channel autocorrelation coefficient to improve the system performance and decrease the feedback complexity.
