Title: Hiroyasu Yoshida: Innovator in Radio Technology
Introduction
Hiroyasu Yoshida is a prominent inventor based in Ota, Japan. He has made significant contributions to the field of radio technology, holding a total of 3 patents. His work focuses on enhancing the efficiency and sensitivity of radio base stations, which are crucial for modern communication systems.
Latest Patents
One of his latest patents is for a diversity receiving radio base station with high reception sensitivity and high time slot utilization efficiency. This invention aims to provide a radio base station that maintains high reception sensitivity without increasing the number of antenna elements, while also ensuring high utilization efficiency of time slots. The design includes a radio unit where two time slots are allocated to a mobile station. After receiving and demodulating a signal from the mobile station, the data is compared to select the piece with fewer errors.
Another notable patent is for a spread spectrum signal receiving apparatus. In this invention, a received spread spectrum signal is despread by a first despreading circuit. A synchronizing signal generator produces a signal in phase with the first despread signal. This output is used to generate multiple spreading codes that are out of phase with one another. A correlation detector then assesses the correlation between the spread spectrum signal and the various spreading codes, allowing for the determination of the optimal phase for accurate despreading.
