Publication number: 20220346026Abstract: The present disclosure relates to a communication apparatus, a communication method, and a program that enable improvement in performance of short-range wireless communication. The communication apparatus includes: a reception circuit that receives a signal transmitted by load-modulating in a card, which is a partner in short-range wireless communication, via an antenna; and a transmission power control unit that controls transmission power transmitted to the card on the basis of a reception signal modulation degree which is a modulation degree of the signal received by the reception circuit. Then, the transmission power control unit performs control so as to reduce the transmission power in a case where the reception signal modulation degree is less than or equal to a certain threshold value. The present technology can be applied to, for example, a communication apparatus that performs short-range wireless communication.Type: ApplicationFiled: October 14, 2020Publication date: October 27, 2022Inventors: Hiroaki Fujita, Hiroaki Nakano, Uichiro Omae

Publication number: 20220291371Abstract: Provided are a distance measurement device and a distance measurement method for accurately measuring a distance even when multipath occurs. The present technology provides a distance measurement device including a first transceiver, a second transceiver, a response information acquisition section, a filter, and a distance calculator. The first transceiver transmits a first pulse signal to the second transceiver while performing frequency sweeping. The second transceiver receives the first pulse signal transmitted from the first transceiver. The response information acquisition section acquires response information on a basis of a phase difference obtained by reception of the first pulse signal. The filter extracts initial response information from the response information, the initial response information being the response information related to the first pulse signal to be received at an initial stage.Type: ApplicationFiled: May 19, 2020Publication date: September 15, 2022Inventors: Masayuki Tanaka, Hiroaki Nakano, Uichiro Omae
