Latest Patents

Among his latest inventions are two notable patents pertaining to CDMA mobile communication systems. The first patent details a radio communication system designed with a base station and multiple radio terminals. Each terminal, upon having a transmission request, transmits a reservation packet at arbitrary timings through a reservation channel based on a CDMA scheme. The base station then assigns a traffic channel and time slot via a reply packet, utilizing a short spreading code that corresponds to a matched filter on the reservation channel.

His second patent introduces improvements to the existing CDMA mobile communication system, ensuring stable reception with minimal bit error rates. This system comprises a base station and a mobile station, where the mobile station features essential components like an oscillator, a radio frequency demodulator, and a radio frequency modulator. The design fosters efficient communication, as the oscillator's frequency is dynamically controlled through detected phase shifts from the demodulated signals received from the base station.
