Abstract

The invention belongs to the field of 5G communication, and relates to a design method of a robust hybrid transceiver for a point-to-point millimeter-wave full-duplex system; the design method includes performing singular value decomposition on an estimated channel to obtain an analog transceiver; The equivalent transmission channel is created, and the digital transmitter is partially initialized through the equivalent transmission channel estimation; the digital receiver is calculated by updating the digital transmitter; the construction based on the updated digital transmitter, analog transmitter and analog receiver is derived from The interference equivalent channel; the null space obtained by carrying out singular value decomposition from the interference equivalent channel as the SIC receiver; 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 , the design gets a hybrid transceiver. The present invention firstly does not consider self-interference, designs a system hybrid transmitter, designs a self-interference elimination matrix and adds it to a receiver, and completes the design of a 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. In recent years, millimeter wave has become the research focus of the fifth generation mobile communication technology because of its rich spectrum resources. It can achieve a communication rate dozens of times that of 4G. In addition, Z. Zhang, K. Long, A.V. Vasilakos and L.
