Embodiment Construction

[0103] In the method for eliminating mutual interference between multiple paired array elements in single-antenna full-duplex communication provided by the present invention, single-antenna multi-dual array elements refer to a common antenna for sending and receiving, and a number of dual array elements are configured, each pair The array element is composed of a positive array element and a negative array element. The positive array element and the negative array element emit the same signal, and the phase difference between the two is 180 degrees.

[0104] The method for eliminating mutual interference between multiple pairs of even array elements in the single-antenna full-duplex communication of the present invention has the following overall idea:

[0105] First, based on the principle of mutual interference cancellation, the basic unit of multi-array element mutual interference cancellation is studied, that is, the hybrid structure of single-array element self-interferenc...

Abstract

The invention discloses a method for eliminating mutual interference between multiple pairs of dual array elements in single-antenna full-duplex communication. According to the overall idea of the invention, the basic unit of multi-array element mutual interference cancellation is studied based on a mutual interference cancellation principle, and an equivalent baseband model for a single-antenna multi-pair dual-array element primary radio frequency channel is established; and positive and negative array element distribution is designed based on a fractal model with a single pair of dual arrayelements as the basic unit, so that fractal array elements that can multi-dimensionally cancel multi-array element mutual interference is formed. According to the method of the invention, a transmitting antenna and a receiving antenna share one antenna, and therefore, part of the antenna and bandwidth resources can be saved; ad mutual interference in simultaneous co-frequency full-duplex communication can be effectively eliminated under the premise that antenna resources are not wasted, and therefore, the spectrum efficiency of the communication can be effectively improved, and spectrum efficiency is higher. The method is suitable for large-scale communication situations.

Description

technical field [0001] The invention relates to a method for eliminating mutual interference between multiple pairs of even array elements, in particular to a method for eliminating mutual interference between multiple pairs of even array elements in simultaneous and same-frequency full-duplex communication of a single antenna, and belongs to the technical field of communication. Background technique [0002] Wireless simultaneous same-frequency dual-source full-duplex transmission refers to the transmission of signals from two source nodes to two destination nodes on the same wireless physical channel, at least one of which is both a source node and a destination node. [0003] Wireless simultaneous and same-frequency dual-source full-duplex is a technology that can effectively improve the communication spectrum efficiency and can be put into practical use in a small-scale communication environment in recent years. Compared with the traditional half-duplex (only one source ...
