摘要
认知无线电作为一种智能无线电技术,可赋予无线通信系统以电磁环境感知能力,有效解决频谱利用率和管理的问题。软件通信体系结构(简称SCA)已被软件无线电论坛采纳为嵌入式系统的标准通信软件结构。SCA提供了一种支持通信软件和硬件可移植、可配置、可扩充和可重用的软件平台。本文首先论述了认知无线电的概念、功能,接着结合开源认知无线电的概念,提出了一种基于SCA的认知无线电台的新结构,并进行了详细的阐述。
As an intelligent wireless communication technology, cognitive radio can sense electromagnetic environment and resolve the utilization and management of radio spectrum resources. SDR Forum has adopted SCA as a standard for SDR embedded systems software. SCA provides a framework that supports portability, configurability, scalability and reusability of SDR software and hardware. In this paper, The definition of the cognitive radio are introduced firstly, as well as the features. Then, on the basis of the concept of open - source cognitive radio, a new architecture of cognitive radio based on SCA are presented.
