Intelligent Radio Concepts
Daniel Chew, Andrew L. Adams, Jason Uher · 2021
This chapter introduces intelligent radio concepts, and aims to establish a set of basic definitions describing the various radio technologies associated with DSA. It presents the desired capabilities of an intelligent communications system in the context of wireless coexistence. The chapter discusses the cognitive cycle at length, but this generally involves the process of observe-orient-decide-act, and focuses on intelligent-radio rather than cognitive-radio. The implementation of cognitive capability is very much an active area of research. The cognitive resource manager (CRM) framework is capable of supporting both centralized and decentralized network configurations. The CRM toolbox is a library of algorithms used by the CRM core for data pre-processing, modeling, learning, and decision-making. The chapter discusses several learning algorithms and their recent application to intelligent radio. Advances in automation, machine learning, and artificial intelligence should only increase our expectations regarding intelligent radio capabilities.
