Patent number: 10862594Abstract: A communication system includes one or more communication apparatuses, each including a transmission circuit and a reception circuit. The transmission circuit includes a transmission unit and a signal generator. The transmission unit transmits one of a first transmission signal including first transmission data or a second transmission signal including at least one of a periodic signal with a constant frequency or a narrow band modulation signal having lower speed than the first transmission data. The signal generator generates the second transmission signal. The reception circuit includes a reception unit that receives the first transmission signal and the second transmission signal a narrow band detector that outputs a narrow band detection signal through detecting the second transmission signal in a narrow band, and a determination unit that determines presence of a significant signal or presence of significant signal change in the narrow band detection signal and outputs a determination signal.Type: GrantFiled: May 16, 2017Date of Patent: December 8, 2020Assignee: SONY CORPORATIONInventors: Katsuyuki Tanaka, Fumitaka Kondo, Moonjae Jeong, Toru Terashima, Fumihiro Nishiyama

Patent number: 7190216Abstract: In a sampling block 40a-1, an intermediate frequency signal RIFs is sampled at a frequency of the intermediate frequency signal RIFs multiplied by “1/(m+0.25)” or “1/(m+0.75)” (m: 0 or natural number), to generate signals having phase differences “0”, “?/2”, “?”, and “3?/2”. A polarity adjustment block 40a-2 matches a polarity of the signal having phase difference “?” with that of the signal having phase difference “0”. Further, it matches a polarity of the signal having phase difference “3?/2” with that of the signal having phase difference “?/2”. In a signal synthesis block 40a-3, the signal with phase difference “0” and the signal with phase difference “?” having phase difference “?” from each other are synthesized and held to be output as a demodulated signal PI. Further, the signal with phase difference “?/2” and the signal with phase difference “3?/2” having phase difference “?” from each other are synthesized and held to be output as a demodulated signal PQ.Type: GrantFiled: August 22, 2003Date of Patent: March 13, 2007Assignee: Sony CorporationInventors: Kazuyuki Saijo, Moonjae Jeong
