Title: Innovations of Yukihiro Shimakata
Introduction
Yukihiro Shimakata is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of signal processing, particularly in the area of phase-shift keying (PSK) modulation. With a total of 2 patents, his work has advanced the technology used in communication systems.
Latest Patents
One of his latest patents is a circuit for demodulating PSK modulation signals. In this differential-detection demodulator circuit, a PSK modulated signal is compared with a locally oscillated signal to obtain a phase difference between the two signals. The phase difference is then demodulated, and a digital phase detector circuit outputs the phase difference signal. This innovation allows for low electrical power consumption and a simple circuit construction.
Another significant patent by Shimakata is a circuit for demodulating PSK modulated signals by differential detection. This demodulator circuit converts a PSK modulated signal into a quasi-base band signal and then separates it into complex components. The differential-detector circuit processes only the phase angle, resulting in a simple construction. The detected phase difference compensates for errors between the carrier wave contained in the modulated signal and the locally oscillated frequency, outputting a digital demodulated signal.
