Title: Keiichiro Hijino: Innovator in Signal Detection and Synchronization Systems

Introduction

Keiichiro Hijino is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of signal detection and synchronization systems, holding a total of 2 patents. His work has been instrumental in advancing technology in digital transmission systems.

Latest Patents

One of his latest patents is a circuit that detects a signal in successive frames by feeding back look. This signal detection circuit receives a data stream containing a signal to be detected and effectively identifies the contained to-be-detected signal. The circuit includes a memory component that prestores data for detecting the signal, along with two data feeders that manage the input of data to the memory circuit. By organizing the memory circuit to output a specific value when the signal is detected, the circuit achieves successful detection of the desired signal.

Another significant patent is a synchronization system designed for use in digital transmission systems. This system processes an encoded digital transmission signal, which has specific statistical characteristics. The digital transmission apparatus at the receiving end includes a decoder that performs decoding based on a synchronous input signal. It also features a monitor that tracks the internal states of the decoder, determining whether the system is in a synchronous or asynchronous state. If the system is asynchronous, a phase shifter adjusts the relative phase of the digital transmission signal to ensure proper synchronization.
