Title: The Innovations of Masayuki Ariyoshi
Introduction
Masayuki Ariyoshi is a notable inventor based in Mitaka, Japan, recognized for his contributions to communication technology. He holds a total of seven patents, showcasing his innovative spirit and technical expertise in the field of CDMA communications.
Latest Patents
One of his latest patents involves a CDMA communication system and method. In this system, a base station detects the difference between a reference phase of a spreading code and the phase of a received signal from each terminal station. The base station then feeds a phase jump signal, PJ-i, which represents the phase difference back to each terminal station. After timing acquisition, the reception operation is performed using the reference phase. A shift amount between the phase of the received signal and the reference phase is fed back to each terminal station as phase synchronization control information, PC-i. Each terminal station coarsely adjusts the phase of the spreading code according to the phase jump signal PJ-i and subsequently fine-tunes the phase of its transmitting signal based on the phase synchronization control information PC-i. This process allows for the synchronization of the phases of signals transmitted from terminal stations and received at the base station, utilizing an orthogonal code for spreading on the reverse links.
