Title: Innovations by Masashi Iwabuchi
Introduction
Masashi Iwabuchi is a prominent inventor based in Musashino, Japan. He has made significant contributions to the field of radio communication, holding a total of five patents. His work focuses on enhancing communication quality through innovative methods and systems.
Latest Patents
Iwabuchi's latest patents include a radio communication method, a radio communication system, a radio base station, and a reflector. In his radio communication method, communication is performed between a radio base station and a radio terminal via a reflector. The radio base station transmits a measurement signal that includes a beam ID for measuring communication quality. The reflector reflects this measurement signal in multiple directions, generating several reflected measurement signals. It also modulates the incident measurement signal to add information about a reflection direction ID, which is different for each reflection direction. The radio terminal then demodulates the reflected measurement signal to acquire both the reflection direction ID and the beam ID, allowing it to evaluate communication quality for each combination.
Another notable patent is his relay control system, which includes a relay apparatus with multiple reflection elements. These elements apply independent phase shifts to incoming waves. The communication circuitry receives transmission point information, while the element allocation circuitry determines the number of communication links to establish. The phase control circuitry generates a beam directed to a reception point based on the reflection waves produced by the allocated reflection elements.
