Effects of multipath fading on BER statistics in cellular CDMA networks with fast power control

An analytical approach for the calculation of the bit error rate statistics in a cellular code-division multiple access system with imperfect fast pow er control is presented. Usually, imperfections in power control after desp reading 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 accoun t the results obtained are too optimistic.
