Abstract :
In order to decrease the feedback complexity of distributed MIMO system, we consider a simplified feedback, the capacity autocorrelation information (CAI) feedback, and investigate the CAI characteristics in this paper. Results show that the CAI, which can be fed back to the transmitter for adaptive coding and modulation, can be simply predicted by the channel autocorrelation in the distributed MIMO system, which results in even less complexity in the calculation of the feedback information
