精确的功率控制是蜂窝码分多址（CDMA）系统设计中的基本要求。三维空对地蜂窝系统的性能分析是一个重要的研究课题。本文在假设非理想功率控制服从对数正态分布的前提下，对航空通信系统的容量和中断概率进行了研究和量化。在给定中断概率和功率控制误差的情况下，计算了系统容量。从数值结果，它表明，该系统是相当敏感的小功率控制误差。
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.
