Abstract
An analytical approach for the calculation of throughput and delay in a cellular slotted CDMA system with imperfect power control is presented. Power control is essential for such systems for good performance, however, perfect power control is hard to achieve in real systems. Usually, imperfections in power control after despreading are modelled as a lognormal random variable. It has been shown that the standard deviation of this variable is a function of the mobiles velocity and of whether or not the mobile is communicating with the base station where the power is measured. In this work, we show that when this fact is not taken into account the performance analysis results obtained are too optimistic. We use the error statistics to model the intercell interference and evaluate the impact of different mobiles velocity and number of resolvable paths on the system performance.
