Abstract

The invention relates to a robust hybrid transceiver design method based on millimeter wave full duplex relay communication, and belongs to the technical field of communication. The method comprises the following steps of: designing an interference elimination matrix at a relay end by utilizing the null space property of a self-interference channel; and then, using the capacity lower bound of a channel as an optimization problem, solving an all-digital precoder by a water injection algorithm, and integrating an interference elimination matrix into an all-digital precoder at the relay end; andfinally, decomposing the all-digital transceiver into a hybrid transceiver by using an iterative decomposition method with a closed-form solution.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a design method of a robust hybrid transceiver based on millimeter wave full-duplex relay communication. Background technique [0002] As the key technology of the next generation mobile communication system, the millimeter wave communication system has widely adopted the mixed structure of analog and digital transceivers. Compared with high-complexity all-digital transceivers, hybrid transceivers can still provide sufficient beamforming gain and have fewer hardware constraints under large-scale antenna arrays. With the participation of the relay system, the hybrid transceiver design can reduce the attenuation of the transmitted signal and increase the coverage of the network. In addition, compared with half-duplex, the use of full-duplex communication (signals can be transmitted and received at the relay end at the same time) can achieve a higher transmission rate [1].
