Title: Haruhiro Shiino: Innovator in Spread-Spectrum Communication Technology

Introduction

Haruhiro Shiino is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of communication technology, holding a total of 13 patents. His work primarily focuses on spread-spectrum communication systems, which are essential for efficient data transmission.

Latest Patents

One of Shiino's latest patents is a spread-spectrum communication apparatus with adaptive frame configuration. This innovative apparatus transmits and receives packets of data preceded by reference signals used in demodulating the packets. A control unit within the communication apparatus estimates channel conditions and varies the length of the transmitted packets, thereby adjusting the intervals between reference signals. This approach allows for the use of longer packets under better channel conditions, effectively avoiding excessive overhead without compromising the accuracy of channel estimates used in demodulating the received data.

Another notable patent is related to a spread spectrum transmitter and receiver. This system is designed to reduce the number of required matched filters, simplifying the configuration associated with reception. In the spread spectrum transmitter, multiple spread channel signals are synthesized by shifting their respective phases by a time significantly shorter than one symbol period. The spread spectrum receiver then sets a plurality of spread code sequences one by one at a tap of a single matched filter in a time division manner to recover the transmitted data.
