Introduction

Yoshihiko Kuwahara is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of wave parameter measurement, holding a total of 8 patents. His work focuses on enhancing communication technologies through innovative methods and devices.

Latest Patents

Kuwahara's latest patents include a multiple propagation wave parameter measuring method and apparatus, as well as a machine-readable recording medium that stores a multiple propagation wave parameter measuring program. In this method, transmission waves are radiated into outer space and received as multiple propagation waves. The arrival directions of these waves are measured based on reception signals. A desired wave is defined from one direction, while unnecessary waves are identified from other directions. A weight is calculated to maximize the reception power ratio of the desired wave to the unnecessary waves. This allows for the extraction of the reception signal with suppressed unnecessary waves. Additionally, he has developed a direction finder that measures incoming angles of multiple signals without the need for spatially moving antenna elements, making it suitable for outdoor mobile communication environments.
