Title:
NOISE CANCELING DEVICE FOR WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/024426
Kind Code:
A1
Abstract:
Provided is a noise canceling device for a wireless communication system in which a plurality of wireless communication devices which perform half-duplex communication by digital phase modulation are configured as an array. In the wireless communication system, the noise canceling device suppresses a wraparound signal from another wireless communication device by composing, on the basis of the baseband signal of a reception signal, a cancel signal, obtained by controlling at least one of the phase and amplitude of a transmission carrier signal, with a wireless reception signal. The noise canceling device is provided with a control unit that determines whether the number of bits per frame of the baseband signal to be transmitted is odd or even, and that inverts the cancel signal when the number is even.
