COMMUNICATION SYSTEM, COMMUNICATION METHOD, AND COMMUNICATION PROGRAM

Document Type and Number:

WIPO Patent Application WO/2023/181270

Kind Code:

A1

Abstract:

This communication system performs communication while concealing information the contents of which are not wanted to be intercepted. A radio wave transmitting station transmits, at a frequency included in a predetermined frequency band, a communication signal wave including the information the contents of which are not wanted to be intercepted while transmitting a dummy signal wave in the predetermined frequency band. A radio wave receiving station receives a composite wave including the dummy signal wave and the communication signal wave, and extracts the communication signal wave by removing the dummy signal wave from the composite wave. The radio wave transmitting station transmits the communication signal wave in a time frame that is part of a time period during which the dummy signal wave is transmitted.
