Title: Hiroki Sakurai: Innovator in Radio Technology
Introduction
Hiroki Sakurai is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of radio technology, holding a total of 8 patents. His innovative work has paved the way for advancements in radio apparatus and signal generation.
Latest Patents
Sakurai's latest patents include a sophisticated radio apparatus designed to enhance signal processing. This apparatus features a first receiver that amplifies and frequency converts a radio signal received via an antenna, outputting an intermediate frequency (IF) signal. It also includes a detector unit that identifies a preamble signal from the IF signal, a second receiver for amplifying and quadrature demodulating the radio signal, and a demodulator unit that generates a data signal from the I-signal and Q-signal. The control unit intelligently manages the operation of the receivers based on the detection of the preamble signal and the completion of demodulation.
Another notable patent is a signal generating circuit that incorporates an oscillator to produce an oscillation signal. This circuit is controlled by an analog control signal and includes a digital phase detector, a first differentiator, a comparator, and a low-pass filter. The circuit effectively converts digital frequency error information into analog phase error information, which is then output as the analog control signal.
