In this paper, the measurement results of field experiments for correlation reduction precoding with a repetition code in an overloaded MIMO systems are presented. Measurements are conducted in three propagation conditions that are line-of-sight (LOS), non-line-of- sight (NLOS), and a mobile environment. Numerical results obtained through the measurements show that amplitude shift and phase rotation...
Recently, multi-user multiple-input multiple-output (MU-MIMO) systems with spatial precoding have been widely studied. Although they offer various advantages, these systems require accurate downlink channel state information (CSI) at the transmitter and limits the mobility of user terminals. In this paper, we consider MU- MIMO systems which employ collaborative interference cancellation (CIC) between...
