Pseudonoise code tracking loop for a CDMA system with imperfect power control

摘要

In this paper, performance of a pseudonoise (PN) code tracking loop is analysed an simulated for a direct-sequence/code-division-multiple-access (DS/CDMA) system with imperfect power control in a multipath fading channel. A non-coherent first-order delay-locked loop(DLL) is considered as a PN code tracking loop. Power control error is modelled as a log-normally distributed random variable. The multipath fading channel is modelled as a two-ray Rayleigh fading model that is typically applied to land mobile communication environments.
