Reciprocity evaluation based adaptive CCM reconstruction in FDD multi-antenna systems
In view of the difficulty of obtaining downlink channel state information, partial reciprocity based channel covariance matrix (CCM) reconstruction has attracted a lot of attention in frequency division duplex (FDD) multi-antenna systems. Taking both the impact of CCM reconstruction on system perfor...
