Title: The Innovations of Shinzo Ohkubo
Introduction
Shinzo Ohkubo is a notable inventor based in Tokorozawa, Japan. He has made significant contributions to the field of radio communications, holding a total of 5 patents. His work focuses on enhancing communication systems, particularly in the areas of paging and digital modulation.
Latest Patents
One of his latest patents is a radio paging system that includes one or more pagers with a transmitting function. These pagers can transmit a response upward signal to a base station, acknowledging the reception of a paging signal, as well as a pager initiative signal through direct sequence spread spectrum modulation. The system assigns different spreading codes to these signals, allowing the base station to receive them independently. Another significant patent is a robust digital modulation and demodulation scheme for radio communications that reduces errors due to fading while maintaining the characteristics of M-ary modulation. This scheme involves dividing transmission data into blocks and generating orthogonal codes, which are then multiplexed into a signal for transmission.
