Abstract

This paper will give a detailed discussion about the authors view on software defined and cognitive radio. After an introduction on different aspects of software radio and a novel approach on cognitive radio is presented. As proof of concept a software defined cognitive radio demonstrator termed Falcon was built up which is described afterwards. The Falcon is entirely based on a modular signal processing concept. In particular, the receiver deploys modules which process and generate log-likelihood ratio (LLR) signals, hence, providing the capability of a plug-and-play-type reconfigurability.
基于Petri网调度的新型认知无线电概念
本文将详细讨论作者对软件定义无线电和认知无线电的看法。在介绍了软件无线电的不同方面之后,提出了一种新的认知无线电方法。作为概念的证明,一个软件定义的认知无线电演示器被称为猎鹰被建立,这是后面描述。“猎鹰”完全基于模块化信号处理概念。特别是,接收器部署了处理和生成对数似然比(LLR)信号的模块,因此提供了即插即用型可重构能力。
