未来无线通信系统的体系结构研究及物理实现方法

本文从综合各种不同业务以及综合各种不同的无线通信体制的角度引入了未来无线通信系统的体系结构，也是无线异步转移模式（ＡｓｙｎｃｈｒｏｎｏｕｓＴｒａｎｓｆｅｒＭｏｄｅ，ＡＴＭ）的体系结构。这种体系结构试图从更低的层次上将不同的无线通信体制统一起来。在一定前提下，它试图把不同无线通信体制传输一个（或整数个）固定长度的数据包（ＡＴＭ的Ｃｅｌ）的能力抽象成为资源块的概念，通过对资源块的控制实现灵活地访问物理介质。资源块到物理层具体传输方式的映射通过软件无线电技术来实现，从某种意义上讲，软件无线电对无线ＡＴＭ提供一个物理支撑。

Research on Architecture and Physical Platform of Future Wireless Communication Systems

In this paper, we discussed an architecture of future wireless communication systems. Considering the integrating of various wireless services and the compatibility of present and upcoming standards, the architecture should be a kind of wireless ATM based. In this architecture, we try to integrate the various wireless scheme at the lower layer and treat the ability of every scheme transmitting an ATM cell(or integral numbers of cells) as a resource block. By handling the resource blocks, higher layer can access physical medium flexibly. We think that the software radio is the best technique to map the resource block to the specific wireless scheme, that is why we say that the software radio is the physical platform of the future wireless communication systems.
