Design of full-connected hybrid precoding based on an equivalent channel in millimeter-wave massive MIMO system
In order to improve the performance of hybrid precoding scheme based on fully connected structure in millimeter-wave massive MIMO system, a hybrid precoding scheme based on an equivalent channel with two-step design method was proposed.Firstly, the equivalent channel was constructed by combining the...

| description | In order to improve the performance of hybrid precoding scheme based on fully connected structure in millimeter-wave massive MIMO system, a hybrid precoding scheme based on an equivalent channel with two-step design method was proposed.Firstly, the equivalent channel was constructed by combining the analog precoding matrix at the transmitter, the analog combining matrix and the channel matrix at the receiver, and the analog part of the transceiver was designed to maximize the equivalent channel gain.Furthermore, the least squares criterion was applied to derive the digital precoding matrix and the digital combination matrix column by column to design the digital part of the transceiver.Simulation results show that the proposed algorithm can approximate the optimal digital precoding scheme and has lower complexity and stronger fault tolerance. |
