位置和环境感知是认知无线电和网络的两个突出特征，使它们能够与操作环境交互并了解操作环境。介绍了一种具有位置和环境感知引擎的认知无线电体系结构。给出了这两种发动机的体系结构框架及其组件。提出的体系结构是支持高级自主位置和环境感知应用(例如，高级基于位置的服务(LBS))的一种很有前途的模型。讨论了实现这两个引擎的实现选项、设计挑战、问题和潜在的解决方案。提出了一种适用于两种发动机的基本方法，即距离精度自适应。最后，对全文进行了总结，并对未来的研究方向进行了展望。
Location and environment awareness are two prominent features of cognitive radios and networks enabling them to interact with and learn the operating environment. A cognitive radio architecture with location and environment awareness engines is introduced in this paper. Architectural framework of both engines along with their components are presented. The proposed architecture is a promising model to support advanced and autonomous location and environment-aware applications (e.g. advanced location-based services (LBS)). Implementation options, design challenges, issues, and potential solutions for the realization of both engines are discussed. An underlying method for both engines, which is range accuracy adaptation, is presented. Finally, concluding remarks with future research directions are provided.
