Method for designing robust hybrid transceiver of point-to-point millimeter wave full duplex system

Abstract

The invention belongs to the field of 5G communication, and relates to a method for designing a robust hybrid transceiver of a point-to-point millimeter wave full duplex system. The method comprises the following steps: performing singular value decomposition on an estimated channel to obtain an analog transceiver; constructing an equivalent transmission channel for the analog transceiver, and partially initializing a digital transmitter through equivalent transmission channel estimation; acquiring a digital receiver by updating calculation of the digital transmitter; constructing a self-interference equivalent channel based on the updated digital transmitter, analog transmitter and analog receiver; taking a null space obtained by performing singular value decomposition on the self-interference equivalent channel as an SIC receiver; and calculating the product of the analog receiver, the digital receiver and the SIC receiver and the product of the analog transmitter and the digital transmitter, and designing to obtain the hybrid transceiver. The invention designs a system hybrid transmitter without considering self-interference, designs a self-interference elimination matrix and adds the self-interference elimination matrix into a receiver to finish the design of the hybrid transceiver;.

Description

technical field [0001] The invention belongs to the field of 5G communication, and relates to the design of a point-to-point millimeter-wave robust transceiver and the self-interference elimination of the system through zero space, specifically a design method of a robust hybrid transceiver for a point-to-point millimeter-wave full-duplex system. Background technique [0002] In order to meet the needs of future mobile communication services, research on communication technology is moving towards higher frequency bands.
