| 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, channel estimation schemes for SS-CDMA system are evaluated. SS-CDMA realizes the direct access from terminals to the satellite and many users simultaneous transmission using large spreading factor SS-codes. So, high accurate and high efficient pilot multiplexing method is desired. The performance of delay detection, time division multiplexing (TDM) pilot and code division multiplexing (CDM) pilot have been evaluated in AWGN channel with computer simulation. We show the trade-off among the number of multiplexing user, SNR and expected maximum frequency offset. Additionally, we reveal that the influence of phase noise is less than 1.0 dB $E_b/N_0$ degradation. | |
