Abstract(in Japanese) (See Japanese page)
Abstract(in English) An acquisition scheme using a priori information for DS-CDMA was formerly proposed. In this paper, for realizing more accurate Long code phase estimation complex cross-correlation method and averaging a priori information are evaluated. Average aquisition time and standard deviation of the proposed sheme in Rayleigh fading environment are evaluated. Computer simulation results show that thismethod can reduce the aquisition time less than 50% compared to the conventional serial search method.
