摘要

提出了一种面向认知无线电系统的功能管理体系结构。它依赖于先前定义的多标准SDR系统的配置管理体系结构,并补充它以支持认知无线电功能。本文阐述了认知无线电系统在重构、智能和感知能力方面的要求。提出了一种配置管理体系结构,能够处理SDR系统所期望的硬件异构性和广泛的重新配置场景。管理分布在整个系统上,分层依赖关系设置在3层上,每层都有不同级别的系统知识和它所监督的元素的相关硬件约束。然后,一个认知管理的功能架构从前一个衍生出来,复制了三层层次结构。讨论了每一层元素的角色,以及它们各自的交互以及它们与配置管理体系结构元素的关系

From a Configuration Management to a Cognitive Radio Management of SDR Systems
This paper proposes a functional management architecture for cognitive radio systems. It relies on a previously defined configuration management architecture for multi-standard SDR systems, and complement it to support cognitive radio features. This paper explains the requirements of cognitive radio systems in terms of reconfiguration, smartness and sensing capabilities. A configuration management architecture capable of dealing with the hardware heterogeneity and a wide range of reconfiguration scenarios expected with SDR systems is presented. The management is distributed over the system and a hierarchical dependency is set on 3 layers, each having a different level of knowledge of the system and the associated hardware constraints of the elements it supervises. Then a cognitive management functional architecture is derived from the previous one, copying the 3 layers of hierarchy. The roles of the elements of each layer are discussed, as well as their respective interactions and their relationships with the elements of the configuration management architecture
