Impacts of Power Control on Outage Probability in CDMA Wireless Systems
Kenji Leibnitz · 2000
In this paper we analyze the power control loops on the reverse link of a CDMA system. We obtain an expression for the transmission power of a mobile station and its signal-to-interference ratio (SIR) received at the base station. This allows the derivation of outage probability, which is the probability for not fulfilling the SIR requirements. We will show that power control in the North-American IS-95 system is very robust and that the number of users in the cell does not have much influence on outage. Furthermore, we compare outage which is an event at the receiver with the mobile station exceeding its maximum transmission power.
