几种多址方式的蜂窝移动通信系统容量比较

Capacity Comparison Among the Cellular Mobile Communication Systems of Different Multiple Access Techniques

系统容量是衡量蜂窝移动通信系统性能的重要指标。文章在同等条件下对不同多址技术下的蜂窝移动通信系统容量进行了比较。通过第三代移动通信可选方案之一的多载波CDMA在系统容量上与前两代相比的优越性,展示了其良好的前景。

System capacity is an important cri-terion to scale the performance of cellu-lar mobile communication system.Th is paper makes a capacity comparison a -mong the cellular systems of differe nt multiple access techniques under eq uiv -alent conditions .The result demon-strates that MC -CDMA,one of the schemes which can be used in the 3G mobile communication,has more capa c -ity than others do ,and bring s forth a prospective future .
