Downlink SU-MIMO Beamforming Strategy for Non-ideal Channel Reciprocity in TD-LTE
摘要
Abstract
The channel information time-varying character,asymmetric cell interference and the RF paths in antennas and the baseband module between uplink and the downlink will worsen the application of reci-procity and reduce the beamforming gain in TD-LTE system. Aiming at designing pre-coding for non-ideal reciprocity,a cost function with maximizing the Signal-to-Interference plus Noise Ratio(SINR) in statisti-cal average way is proposed. The regularization matrix pencil is deduced with the statistical correlation ma-trix of the prior channel state information(CSI) matrix and the reciprocity mismatch error matrix. The pre-coding matrix designing can be translated to the deriving generalized eigenmatrix. The simulation shows that the algorithm can build a robust system.关键词
