Abstract

We have proposed synchronized Spread-Spectrum Code-Division Multiple-Access (SS-CDMA) communication for location and short message communication system using Quasi-Zenith Satellite System (QZSS) as a safety confirmation system at the time of grade disaster. In this communication, the satellite reception timings of all uplink signals are synchronized using transmission timing control method in order to realize high-density user multiple access. Transmission timing control is performed using positioning / timing information obtained from QZSS and Global Positioning System (GPS). In this paper, we construct a transmission timing control system using Field Programmable Gate Array (FPGA) and evaluate transmission timing control error. As a result of the measurement, it is found that the transmission timing control error increases in proportion to the delay time, and it affects the satellite reception timing of the signal.
