Low complexity spectrum sensing for cognitive radio enabled aeronautical communication systems
Koodathumkal Mathew Libin · 2020
Air traffic has seen tremendous growth over the last decade and is expected to grow continuously. The state of the art of current aeronautical communication system is not capable of handling future developments due to the scarcity of the spectrum resources and demands enhanced air traffic management schemes. The L-band Digital Aeronautical Communication System (LDACS) is gaining traction as a scheme of choice and aims to exploit the capabilities of modern digital communication techniques and computing architectures. To improve the quality of air traffic management, the spectrum required to be used efficiently. Cognitive Radio (CR) based approaches have also been proposed for LDACS to improve spectrum efficiency and communication capacity. The CR-based system enables opportunistic and on-demand access to L-band channel(s) while meeting the reliability and safety requirements.
