Title: Makoto Taromaru: Innovator in Diversity Receiver Technology
Introduction
Makoto Taromaru is a prominent inventor based in Fukuoka-ken, Japan. He has made significant contributions to the field of communication technology, particularly in the development of diversity receivers. With a total of 5 patents to his name, Taromaru's work has had a substantial impact on enhancing signal quality in various applications.
Latest Patents
One of Taromaru's latest inventions is a diversity receiver designed with a simplified construction that ensures excellent receiving signal quality, even under low fading speeds. This innovative receiver utilizes a signal from a receiving unit that detects receiving signal intensity. An antenna changeover occurs when the signal intensity falls below a predetermined threshold. If the signal intensity remains low after the first changeover, a second changeover is executed, with a longer lapse time set to prevent immediate subsequent changes.
Another notable patent focuses on adaptive array diversity reception, which achieves high convergence speed through simple signal processing. In this design, signals received by multiple antennas are converted into baseband signals and combined using a complex multiplying section and adder. The weight of the complex multiplying section is calculated by a dedicated weight calculating section, which employs a variable step size in its least mean square algorithm. This approach enhances the convergence speed of weight updating while maintaining the same computational load as traditional methods.
