Performance of Cellular CDMA System on Multipath Fading Channel and Imperfection Power Control with LES Antenna Arrays

Abstract

This paper presents the performance of bit error rate (BER) statistics in a cellular  CDMA system which employs a LES array of Smart antenna for improving the quality of service impact of multipath fading channel and imperfect power control. The imperfection in power control is modeled as a lognormal random variable. The standard deviation of this variable depends on the mobile velocity. The number of fading resolvable paths and the measured power of the communication between the mobile and the base station, Numerical results clearly show the bit error rate is deceased as the number of antenna elements increases.
