Document Type and Number:
WIPO Patent Application WO/2023/075061
Kind Code:
A2
Abstract:
The present invention relates to a closed-loop multi-antenna system and a closed-loop multi-antenna communication security method therefor, wherein the closed-loop multi-antenna system may comprise: a modulation unit which generates a plurality of transmission signals by modulating data bits; a pre-distortion unit which pre-obtains and shares channel phase information and pre-distorts the plurality of transmission signals by using the pre-obtained channel phase information; a transmission unit which wirelessly transmits the plurality of pre-distorted transmission signals through a multi-antenna; a reception unit which obtains a received signal by receiving a signal transmitted wirelessly from a transmission side; a distortion information calculation unit which receives and stores pre-shared channel phase information and calculates distortion information by using the pre-shared channel phase information; and a demodulation unit which removes distortion of the received signal by using the distortion information, and then demodulates the received signal into original data bits.
