Title: The Innovative Contributions of Tomoaki Hirota

Introduction

Tomoaki Hirota is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of technology, particularly in the areas of communication and signal processing. With a total of 2 patents, Hirota's work has had a notable impact on the industry.

Latest Patents

Hirota's latest patents include a rate determination apparatus and a reception apparatus. The rate determination apparatus features a reception unit designed to receive a transmission frame modulated by an FSK modulation scheme. It includes a symbol rate detection unit that detects a symbol rate based on the period of a preamble portion in the received transmission frame. Additionally, a multilevel symbol detection unit is incorporated to detect a multilevel-modulated symbol based on frequency deviation. The bit rate determination unit then determines the bit rate based on the detected symbol rate and multilevel symbol, allowing for effective communication.

The second patent, a radio receiver and intermediate frequency selection method, enables the reception of a radio frequency signal in an intermediate frequency mode that is suitable for varying radio wave reception conditions. This invention utilizes a variable frequency oscillator and a quadrature demodulator to generate an intermediate frequency signal. An ADC converts the intermediate frequency signal into a digital signal, while a mode control section switches the operating mode of the quadrature demodulator based on reception conditions.
