Introduction

Koji Kitahara is an inventor based in Yokohama, Japan. His work includes inventions in signal processing and optical communications. He is associated with 4 patents.

Latest Patents

Kitahara’s listed patents address bit-rate detection and optical signal modulation.

“Bit-rate discrimination method and its apparatus” describes a way to identify a signal’s bit rate by detecting repeated patterns in a preamble. The method converts repetitions of an identical pattern into a longer consecutive signal, enabling faster discrimination than conventional integration-based circuits.

“Modulation method, modulation program, recording medium, modulation device, and optical transmitter” concerns optical transmitters in which a light source is driven by a differential signal. A control circuit balances transient potential fluctuations between the normal and reverse phases, helping the transmitter send an optical signal reliably even before the input potentials have stabilized.
