In this paper, we consider the design of low-complexity analog-digital hybrid transceivers for a multi-input multi- output (MIMO) millimeter wave (mmWave) communication system operating in a $K-$user interference channel. Our objective is to achieve the energy efficiency by minimizing overall transmit power required for achieving a target mean- square error (MSE) at the receivers. We propose two transceiver designs based on the quality of the available channel state information (CSI). We first present a design that minimizes total transmit power assuming the availability of perfect channel knowledge. Later, we extend it to a robust transceiver design by considering imperfections in CSI. The proposed designs achieve reduced hardware and computational complexity by forming hybrid architecture using sparse signal processing. Hence, achieving similar MSE with lower energy consumption. We evaluate the performance of both the proposed schemes based on various parameters. Furthermore, we demonstrate the resilience of the robust design in presence of errors in CSI and performance of both the designs with various dictionaries.
