TY - JOUR AU - Kim, Suk AB - To achieve a far higher capacity in massive multi-input multi-output, the hybrid analog and digital precoding has been studied recently. In this paper, we consider the downlink single user communication system and propose an efficient matrix adaptive gradient descent algorithm to design the radio frequency precoder and combiner, and use the singular value decomposition method to obtain the digital precoder and combiner. Simulation results show that the proposed method can approach the performance of the conventional full digital precoding with a fast convergence rate.
