Introduction

Minoru Okada is a notable inventor based in Minoo, Japan. He has made significant contributions to the field of signal processing, particularly in the area of multi-frequency quadrature modulation. With a total of 2 patents, Okada's work has advanced the understanding and application of complex signal demodulation techniques.

Latest Patents

Okada's latest patents include a method of demodulating a multi-frequency quadrature modulated signal. This innovative method involves dividing a multi-frequency quadrature modulated signal into several frequency bands. Each frequency band component is estimated for phase variation due to multi-path phasing, utilizing its guard interval waveform to compensate for this variation. Another significant patent is for a channel separating filter apparatus and PSK demodulator apparatus. This invention describes a channel separating filter apparatus designed to separate a frequency-multiplexed signal into its respective channel signals. The frequency-converting section frequency-converts the frequency-multiplexed signal into multiple channel signals, ensuring that the average value of carrier wave frequencies of two adjacent channel signals becomes substantially zero.
