چکیده
AbstTactIn this paper, performance of PN code acquisition is analyzed for a DS/CDMA overlay system with imperfect power control. Acquisition performance is evaluated in terms of mean acquisition time using state transition diagram for acquisition process. To apply for a DS/CDMA cellular environments, the MA1 and imperfection of power control are taken into account in the analysis of acquisition performance. The imperfect power control is considered by modelling the power of each user to be lognormally distributed about nominal received power. A narrowband user is modelled as a narrowband interference located at the fraction of a CDMA user’s bandwidth. The analysis in this paper can be applied to the practical situations for a DS/CDMA overlay environment.

We analyze the performance for reverse-link synchronous DS-CDMA system in a frequency-selective Rayleigh fading channel with an imperfect power control scheme. The performance degradation due to power control error (PCE), which is approximated by a log-normally distributed random variable, is estimated as a function of the standard deviation of the PCE. In addition, we investigate the impacts o...
