Title: FULL-DUPLEX WIRELESS COMMUNICATION DEVICE, METHOD AND SYSTEM
Abstract:
The present invention is applied to the technology field of wireless communications and provides a full-duplex wireless communication device, method and system, the method comprising that transmitting signals are output by the first polarization antenna of dual polarization antennas, and the second polarization antenna acquires receiving signals which include useful signals and the first transmitting sub-signals coupled directly from the first polarization antenna; the analog domain elimination module acquires the second transmitting sub-signals coupled from the transmitting signals, modulates the amplitude and phase parameters of the second transmitting sub-signals in order to transform them into the third transmitting sub-signals, eliminates the first transmitting sub-signals according to the third transmitting sub-signals, samples the receiving signals from which the first transmitting sub-signals are eliminated as the first digital signals, simultaneously samples the second transmitting sub-signals as the second digital signals, and outputs the first digital signals and the second digital signals to the digital domain elimination module; and the digital domain elimination module eliminates the second digital signals from the first digital signals, so as to reduce the interference signals effectively.
