Title: Toyokazu Hori: Innovator in OFDM Technology and Semiconductor Design
Introduction
Toyokazu Hori is a prominent inventor based in Kodaira, Japan. He has made significant contributions to the fields of telecommunications and semiconductor technology. With a total of 5 patents, Hori's work focuses on enhancing data transmission methods and integrated circuit devices.
Latest Patents
Hori's latest patents include an OFDM demodulation method and a semiconductor integrated circuit device. The OFDM demodulation method involves processing for receiving an OFDM packet that contains a preamble and subsequent data transmission symbols. In this method, the subcarrier interval of the preamble is wider than that of the data transmission symbol. The process includes estimating a DC offset at the receiving side using the received preamble, correcting the DC offset on the received data transmission symbol based on this estimation, and demodulating the corrected data transmission symbol. This innovation allows for effective DC offset estimation and correction in OFDM packets without defined nul symbols. Additionally, the semiconductor integrated circuit device is part of a wireless LAN system that features auto gain control without imposing a workload on its baseband processing block. The gain control circuit in this system switches between receiving antennas and adjusts gain settings based on the level of the received signal.
