摘要：
Three methods of determining the Erlang capacity of a cellular CDMA uplink system are presented. The first method decouples the analysis of blocking and outage performance, and avoids iterative search. Based on two approximations regarding the mobile traffic and the interference, the second method jointly examines blocking and outage performance. The third, more detailed, method considers the mobile traffic characteristics and the interference with mobile traffic fluctuations. The Erlang capacity of a cellular CDMA uplink system using a power control scheme called truncated channel inversion is calculated with each of the methods. The methods are also used to compare the Erlang capacities for different power control schemes.
