摘要
从编码理论和话务理论出发 ,分析了三值CDMA移动通信系统的系统容量。证明在信息传输速率一致的条件下 ,三值系统的无线容量约为二值系统的log2 3(约 1 6 )倍 ;在码元传输速率一致的条件下 ,三值系统的服务等级更高。可见 ,三值CDMA系统为解决现有移动通信系统容量不足的问题开辟了新的途径。
In this paper,the analysis of ternary CDMA cellular mobile communication system capacity is based on coding theory and telephone traffic theory .The result shows that the wireless capacity of ternary system is about 1.6 times that of binary system on the presumption at equal information transmission rate.On the other hand,on the assumption that two systems are at equal code transmissin rate ,the service quality of ternary system is more satisfactory.Therefore,ternary CDMA system,to some extent,opens the way to resolve the trouble resulted from the insufficient capacity of current mobile communication system.
