Title: Koichi Masuda: Innovator in Optical Transmission Systems
Introduction
Koichi Masuda is a prominent inventor based in Hirakata, Japan. He has made significant contributions to the field of optical transmission systems, holding a total of 2 patents. His work focuses on enhancing the efficiency and reliability of communication systems.
Latest Patents
Masuda's latest patents include a multi-point optical transmission system and an optical transmission unit. The multi-point optical transmission system allows radio base stations to subject each code-division multiplex signal to frequency conversion. This process varies each frequency according to the radio base stations and converts the signal to an optical signal before transmitting it to a switching station. The switching station then multiplexes the optical signals and performs optical-electrical conversion, ensuring that the code-division multiplex signal from a desired base station is not disturbed by signals from other stations.
The optical transmission unit involves an AM signal source that frequency-multiplexes and outputs multiple AM signals. A soft clipper nonlinearly limits the large amplitude portions of the frequency-multiplexed AM signal. An attenuator adjusts the signal level for optical modulation. Additionally, a 16QAM signal source frequency-multiplexes and outputs several 16QAM signals with different carrier frequencies. The optical transmitter then intensity-modulates a laser output beam with the frequency multiplex signal, ensuring no clipping distortion occurs during transmission.
