Title:
WIRELESS COMMUNICATION METHOD, WIRELESS COMMUNICATION SYSTEM, AND TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/157143
Kind Code:
A1
Abstract:
This wireless communication method includes a phase shift amount determination process for determining a random phase shift amount for each sub-carrier of transmission data. The wireless communication method also includes a modulation process for modulating the transmission data and further shifting the phase in accordance with the random phase shift amount for each sub-carrier. The wireless communication method further includes: a pre-coding process for pre-coding the transmission data after the modulation process; and a transmission process for transmitting the transmission data after the pre-coding process from a transmission device to a reception device.
