摘　　要：干扰和CDMA蜂窝系统的性能有关,须分析计算其他小区干扰因子(OCIF)。本文通过航空通信系统的OCIF计算进行数据包传输下行链路的性能研究,并分析了系统容量、数据包传输成功率和数据包传输延迟。从数据分析的结果可以看出航空通信系统的性能不如陆地蜂窝系统,并且与小区半径和高度成对数函数关系。Since the interference is quite related to the performance of CDMA cellular systems, it is necessary to estimate Other-Cell- Interference Factor （OCIF）. Here, starting from OCIF calculation for an aeronautical communication system, we investigate the forward link performance of data packet transmission in which the capacity, throughput and delay of the system are measured. To the numerical results, one can see that the performance of the aeronautical communication system is worse than that for terrestrial cellular systems and also depends logarithmically on both the cell radius and height.
