Abstract (in Japanese) (See Japanese page) 
(in English) Quasi-Zenith Satellite System (QZSS) is expected to provide a high accurate positioning service and allows two-way communication which includes the terminal location and short messages. In this paper, SS-CDMA system performance with frequency offset among terminals and phase noise is evaluated.
SS-CDMA realizes the direct access from terminals to the satellite and many users simultaneous transmission using large spreading factor SS-codes. In order to achieve this objective, keeping orthogonality among all terminals is important issue. We propose a novel transmit AFC (Automatic Frequency Control) method in which all terminals are synchronized in time and frequency domains using QZSS. BER performances in 1024 chip SS-code and 1000 user multiplexing condition are shown. Each user is assigned 1 chip rotational shift SS-code based on an orthogonal M-sequence. 1/8 normalized frequency offset in symbol rate can provides the performance with less than 1.0 dB $E_b/N_0$ degradation.
