Title: Innovations of Kazunori Motohashi: A Pioneer in Communication Systems
Introduction
Kazunori Motohashi, located in Tokyo, Japan, is a distinguished inventor with a remarkable portfolio of 20 patents. His work primarily focuses on advancements in communication systems, making significant contributions to the field.
Latest Patents
Among his latest inventions are the 'Matched filter for spread spectrum communication systems' and 'Hybrid analog-digital transversal filter.' The matched filter invention offers a low power consumption solution for processing signals received at input terminals. By utilizing a shift register with stages equating to the spread code length, the invention converts signals into digital form through an A/D converter. XOR operations are then performed between the outputs and corresponding spread code bits. The final output is an analog sum produced by an analog adder.
The hybrid analog-digital transversal filter leverages analog operation circuits to enhance operational accuracy and minimize residual charge impact. Input signals are sampled and held in sample-and-hold circuits, where they are multiplied by coefficients stored in a shift register. Additionally, measures are implemented to prevent sample data transmission errors by managing the shifting of coefficients. This innovative design aims to optimize circuit performance through sequential refreshment of operational components.
