Title: Yasuhiko Ito: Innovator in Satellite Communication and Acoustic Technology
Introduction
Yasuhiko Ito is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the fields of satellite communication and acoustic technology. With a total of 3 patents, his work reflects a commitment to advancing technological solutions.
Latest Patents
One of Yasuhiko Ito's latest patents is a hybrid modulation satellite communication system. This system includes multiple small earth stations, a relay earth station, and a satellite. Information transmission is achieved through primary modulation of the carrier wave, while the operation status of each small earth station is transmitted via secondary modulation. The primary modulation can be BPSK or multiphase PSK, and the secondary modulation may include PSK, ASK, or FSK. The system is designed to ensure that the receive signal quality at small earth stations meets desired criteria, even in the presence of rain attenuation.
Another notable patent is the acoustic surface wave filter bank. This invention consists of one or more piezoelectric substrates on which multiple acoustic surface wave filters are fabricated. Each filter includes an input and output interdigital transducer. The design ensures that the center frequencies of adjacent filters do not overlap, effectively attenuating leaked acoustic surface waves from neighboring filters.
