Latest Patents

Ralph W. Schoolcraft holds a patent for a "Pseudo-noise modem and related digital correlation method." This invention involves a correlation and demodulation method and apparatus that utilizes received signals correlated with locally generated pseudo-noise codes. The method maintains correlation measurements across multiple time bins, which correspond to signals received over various paths. Unlike traditional methods that select a limited number of significant correlation measurements for data demodulation, Schoolcraft's invention performs data demodulation over multiple time bins. It then selects and combines data values based on their significance and relative strengths determined during correlation. This approach enhances signal quality and continuity, especially in multipath conditions, and allows for a compact and portable implementation of transmitter and receiver modules.
