摘要

我们探索了在CDMA混合蜂窝架构中使用一种新的双工方案-空间分割双工(SDD)，以支持对称数据服务和非对称数据服务，前者由FDD常规单元提供服务，后者由SDD皮单元(系统I)提供服务。使用每个单元容量作为我们的测量，系统I的性能被评估并与另外两种方法(系统II和系统III)进行比较，其中系统II在常规蜂窝和皮cell中使用FDD，而系统III只是在常规蜂窝架构中使用FDD来服务对称和非对称数据用户。

A CDMA mixed cellular architecture with space division duplex (SDD) for symmetric/asymmetric wireless communications

We explore the use of a novel duplex scheme-space division duplex (SDD) in a CDMA mixed cellular architecture for supporting symmetric data services and asymmetric data services with the former served by FDD regular cells and the latter served by SDD picocells (System I). Using per-cell capacity as our measure, the performance of System I is evaluated and compared with two other approaches (System II and III) in which System II utilizes FDD in both regular cells and picocells and System III simply utilizes FDD in a regular cellular architecture to serve both symmetric and asymmetric data users.
