We present a simple, yet general channel model for MIMO communications with polarization. The channel model is based on covariance matrices and can model a MIMO channel for an arbitrary spatial antenna configuration with arbitrary polarization angles for each antenna element. We also present a method for deriving equivalent spatial transmit and receive covariance matrices that can be used to understand...
The treatment of channel state information (CSI) is critical in the design of MIMO systems. Accurate CSI at the transmitter is often not possible or may require high feedback rates. Herein, we consider the robust design of linear MIMO transceivers with perfect CSI either at the transmitter or at both sides of the link. The framework considers the design problem where the imperfect CSI consists of...
The problem of channel estimation for spatially correlated fading multiple-input multiple-output (MIMO) channels is considered. Based on the channel's second order statistic, the minimum mean-square error (MMSE) channel estimator that works with the superimposed training signal is proposed. The problem of designing the optimal superimposed signal is then addressed and solved with an iterative global...
