On the Capacity and Outage Probability of an Air-Ground CDMA Cellular System with Imperfect Power Control

Accurate power control is an essential requirement in the design of cellular code division multiple access (CDMA) systems. The performance analysis for the three-dimensional air-to-ground (AG) cellular system becomes an important issue. In this paper, assuming that the imperfect power control follows log-normal statistics, the capacity and outage probability of the aeronautical communication system are examined and quantified. The system capacity is calculated with a given outage probability and power control error. From the numerical results, it is shown that the system is rather sensitive to small power control errors.
