摘要
通过对蜂窝系统的载干比的分析，计算了各种蜂窝系统的频率复用系数和系统容量。由码分多址（ＣＤＭＡ）蜂窝系统与其它蜂窝系统的容量的比较可知，ＣＤＭＡ蜂窝系统的频率复用效率约为６２％，其系统容量优于其它蜂窝系统。
The frequency reuse factor and the capacity of cellular systems are derived by analyzing and calculating the carrier to interference power ratio in the cellular radio system. The capacity of code division multiple access (CDMA) cellular system is compared with that of other systems. The comparison shows that the frequency reuse efficiency of CDMA system is about 62%, and the capacity of CDMA is larger than that of other systems.
