Title: Kazuhiko Shibuya: Innovator in MIMO Systems
Introduction
Kazuhiko Shibuya is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of telecommunications, particularly in the development of MIMO (Multiple Input Multiple Output) systems. With a total of 7 patents to his name, Shibuya's work has had a substantial impact on improving communication technologies.
Latest Patents
One of Shibuya's latest patents involves a MIMO system that includes a transmitter and a receiver designed to enhance overall Bit Error Rate (BER) characteristics. The transmitter maps data distributed among transmit antennas onto an IQ plane to generate carrier symbols. It then applies inter-polarization interleave processing in a time direction to these carrier symbols, resulting in the generation of OFDM (Orthogonal Frequency Division Multiplexing) signals. The receiver demodulates these OFDM signals to produce complex baseband signals and subsequently applies a first deinterleave processing in a time direction to generate time deinterleaved data. Furthermore, the receiver executes MIMO separation processing on the time deinterleaved data to create multiple sets of MIMO separated data, followed by a second deinterleave processing between the receive antennas to generate carrier symbols.
Career Highlights
Kazuhiko Shibuya has worked with notable companies such as Nippon Hoso Kyokai and NHK Engineering System, Inc. His experience in these organizations has allowed him to refine his skills and contribute to groundbreaking innovations in the telecommunications sector.
Collaborations
Throughout his career, Shibuya has collaborated with esteemed colleagues, including Taiji Nishizawa and Yutaka Tanaka. These partnerships have fostered a creative environment that has led to the development of advanced technologies.
Conclusion
Kazuhiko Shibuya's contributions to MIMO systems and telecommunications are noteworthy. His innovative patents and collaborations with industry professionals highlight his role as a key figure in advancing communication technologies.
