全频谱深度认知理论与方法
Theories and Methods of Full-spectrum Deep Cognition
摘要
Abstract
The field of full-spectrum cognition and intelligent utilization is deeply studied,and the advantages of existing cognitive radio theories and wireless monitoring technologies in specific environments are emphasized.However,it is also pointed out that the challenge of"shallow understanding"exists when facing broadband,transient,unknown and complex electromagnetic environments.To address this challenge,multi-dimensional deep spectrum cognition is proposed as a future developing direction,which focuses on precise cognition of radiation source targets through dual dimensions involving signal multi-dimensional features and individual intrinsic properties.By exploring the multi-domain characteristics of radiation source target signals and constructing a comprehensive characterization database,the intrinsic property cognition of communication terminals is realized,enabling a more comprehensive understanding and utilization of spectrum resources.The current research status of signal modulation recognition and protocol analysis in modulation domain and protocol domain is analyzed,and the development bottlenecks and key research directions for high-speed target signal recognition and spatial directional cognition are explored.A comprehensive theoretical framework and methods are provided,laying a foundation for future multi-dimensional electromagnetic environment perception and spectrum utilization.关键词
