摘要

提出了自适应双工的思想

基于该思想设计了一种新型的自适应非对称频分双工(AFDD

asymmetric frequency division duplex)传输方案。该方案综合考虑了未来移动通信中上下行链路业务非对称的特点以及电磁辐射对移动通信可能造成的影响

提出了一种自适应非对称双工以及频带分配方案。该方案具备传统FDD系统的优点

同时又具备了一定的TDD系统资源动态自适应调配的能力

可以提高频谱利用率。将AFDD与CDMA结合

证明了其相对于传统上下行等带宽系统可以获得性能上的提升。

Abstract

The concept of adaptive duplex was introduced.Based on it

a novel adaptive duplex transmission technique-asymmetric frequency division duplex（AFDD） was proposed

which considers the asymmetric characteristics of future communications system both in service demand and electromagnetic radiation effects.AFDD has the advantage inheriting from FDD;furthermore

it can allocate frequency resources in downlink and uplink dynamically like TDD which increases the usage efficiency of radio resources.Applying AFDD to CDMA communication system

it is proved that AFDD improves that system’s performance compared with FDD.
