Title: Norio Tomiyoshi: Innovator in Wireless Communication Technology
Introduction
Norio Tomiyoshi is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of wireless communication technology. With a total of 2 patents, his work has had a notable impact on mobile communication systems.
Latest Patents
One of his latest patents is for a wireless base station and mobile station. This invention describes a wireless base station that forms a cell adjacent to another cell created by an adjacent wireless base station in a mobile communication system. A notification unit is included, which informs about time difference information within the cell formed by the wireless base station itself. This time difference information indicates the difference between a predetermined frame transmitted from the wireless base station and an adjacent predetermined frame from the neighboring wireless base station.
Another significant patent is for a diversity receiving device and method thereof. In this invention, signals from antennas A and B are alternately switched by an antenna switch at a predetermined rate. The signals from these antennas are then alternately input to a wireless receiving unit. This unit orthogonal-signal-detects the signals received and inputs the detected signals to a branch selecting unit. The branch selecting unit extracts signals from either of the antennas and transmits them to a matched filter. A searcher obtains despreading timings from correlation values and stores them in two memories, ultimately performing RAKE reception.
