Summary:
In this paper, we present an approximate analysis method for computing the call blocking probability and Erlang capacity of CDMA systems. The approximated results provide only a few percent difference from the exact values, while reducing the calculation complexity. For CDMA systems with 3 sectors, we also show that the system performances such as call blocking probability and Erlang capacity can be characterized just with two traffic parameters (the traffic load of the most loaded sector and the sum of traffic loads of the other remaining sectors) instead of three sector traffic loads especially when the required call blocking probability is given less than 2e^{2}, which makes the traffic engineers manage the system more easily.
