It is well known that the capacity of code-division multiple-access (CDMA) systems degrades rapidly with the increase in power control error. Capacity is also affected by small-scale fading such as Rayleigh fading and by the voice activity. The main contribution of this letter is to provide a new simple approximation to the outage probability of the uplink of a CDMA system utilizing an antenna array for space diversity, taking into account stochastic models of the power control error, small-scale fading, and voice activity.
