Latest Patents
Among Shimoda's latest innovations are two pivotal patents that reflect his expertise in demodulation technology. The first, a **demodulation method and demodulator**, provides an innovative approach to converting analog signals from recorded information into digital signals, ensuring accurate data generation even when working with signals that possess a low signal-to-noise (S/N) ratio. His method involves over-sampling through an A/D converter, which utilizes interpolation computation to reproduce a digital signal synchronized with an appropriate clock. The method effectively employs maximum likelihood detection and RLL decoding, complementing it with error correction codes to rectify potential inaccuracies.
His second noteworthy patent focuses on a **phase synchronization method for extended partial response**, which incorporates a specific clock acquisition pattern using the (1, 7) RLL code known as “100.” This invention allows for rapid phase error computation by temporarily assessing the sample output and appropriately adjusting computational judgments based on the identified state transitions. The refined method not only accelerates phase acquisition despite undefined amplitudes but also enhances overall judgment accuracy by reducing the number of judgment states involved.
