Research on CDMA parallel acquisition in the presence of multi path fading and multi user interference
Jun Chen · Journal of Hefei University of Technology · 1999
This paper investigates the CDMA acquisition method based on parallel architecture with focus on the multi path fading and multi user problems existing in the mobile communication environment.The mathematical channel model and acquisition system model are presented. The mean acquisition time is calculated using state transform function.The statistic distribution of the judge variable is carefully analyzed by considering the ensemble effects of fading,PN code autocorrelation,multi user interference and background noise.
