Regularized Zero-Forcing Precoder for Massive MIMO System With Transceiver I/Q Imbalances

In this letter, we propose a downlink precoder for massive multi-input multi-output (MIMO) system in the presence of I/Q imbalance (IQI) at both base station and user terminals (UTs). We formulate a minimum mean-square error (MMSE) precoding problem with multiple regularization parameters for differ...
