Abstract :
An analytical approach for the calculation of the bit error rate statistics in a cellular code-division multiple access system with imperfect fast power control is presented. Usually, imperfections in power control after despreading are modeled as a lognormal random variable. It has been shown that, in a fading channel, the standard deviation of this variable is a function of whether or not the mobile is communicating with the base station where the power is measured. We show that when this fact is not taken into account the results obtained are too optimistic.
