Abstract

The invention provides a multi-input multi-output transceiver design method and device, and the method comprises the steps: building a target optimization model based on a safety rate model of a user signal in a signal transmission system; solving the target optimization model, and determining optimization design parameters of the transceiver in the signal transmission system; the optimization design parameters comprise at least one of a downlink precoding vector, a downlink artificial noise vector, uplink sending power and a mode selection vector; the security rate model is determined based on signal security rates of all users associated with the eavesdropping device. According to the multi-input multi-output transceiver design method and device provided by the invention, the target optimization model is constructed and solved, so that the optimization design parameters of the transceiver are obtained, interception of signals by eavesdropping equipment can be effectively prevented, and the communication security of a signal transmission system is ensured.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method and device for designing a multiple-input multiple-output transceiver. Background technique [0002] In order to improve the spectral efficiency of the signal transmission system, the existing network-assisted full-duplex system combined with the non-cellular large-scale multiple-input multiple-output technology can integrate the existing simultaneous same-frequency full-duplex, flexible-duplex and hybrid-duplex All access points are connected to the central processing unit through the backhaul, and cooperate to provide services to users. [0003] The access point can work in full-duplex or half-duplex on the same frequency at the same time, but since the interference between the transmitting and receiving antennas of the same access point can be eliminated by analog means, the access point with full-duplex on the same frequency can also be regarded...
