Toshiya Mitomo,Ryuichi Fujimoto,Naoko Ono,Ryoichi Tachibana,Hiroaki Hoshino,Yoshiaki Yoshihara,Yukako Tsutsumi,Ichiro Seto +7 more
TL;DR: In this paper, a 60 GHz receiver (RX) front-end chip fabricated in 90 nm CMOS process is presented, which consists of an LNA, a downconversion mixer, and a phase-locked loop synthesizer.
Patent
Wireless transmitting device and wireless receiving device
TL;DR: In this article, a wireless transmitting device includes a first and a second antenna, a data and a long preamble sequence to estimate a channel response to the first and the second transmitters, and a controller to power on the transmitters at different timings, respectively.
Journal ArticleDOI
Optical subcarrier multiplexing transmission for base station with adaptive array antenna
Ichiro Seto,H. Shoki,S. Ohshima +2 more
TL;DR: In this paper, the authors proposed a radio-over-fiber technique of optical subcarrier-multiplexing transmission for radio base stations (BSs) with adaptive array antennas.
Patent
Radio communication base station system, receiver for radio signal optical transmission and transmitter- receiver for radio signal optical transmission
TL;DR: In this article, the authors proposed a radio communication base station system where a radio information signal is communicated between a central base station provided with a MODEM section whose function can be changed through software and a simple base station mainly consisting of an antenna port, which are interconnected through an optical fiber.
