Patent number: 11929781Abstract: An objective is to provide a terminal device, a communication method, and a communication system in which the time taken by connection operations/authentication operations does not increase proportionally with the pattern length, even if the transmitting side and the receiving side are not synchronized. A terminal device, a communication method, and a communication system according to the present invention create n pieces of signal information (n-bit patterns) by sequentially shifting each bit of a single piece of received signal information (n-bit pattern) one bit at a time. Through the above, signal information time-shifted by one bit each is obtained. Thus, even if the transmitting side and the receiving side are not synchronized, one of the n pieces of signal information is a signal synchronized with the transmitting side. Thereafter, the signal synchronized with the transmitting side can be detected by a brute-force calculation with the patterns (ID information) in the list.Type: GrantFiled: January 23, 2020Date of Patent: March 12, 2024Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Ryota Shiina, Tomohiro Taniguchi, Kazutaka Hara, Shinya Tamaki, Tomoki Murakami, Toshiro Nakahira
