Flight Trial Demonstration of Secure GBAS via the L-band Digital Aeronautical Communications System (LDACS)

Receiver Optimization of the L-Band Digital Aeronautical Communication System

In this thesis, we consider the interference cancellation problem for the broadband digital aeronautical communication system. We investigate the L-band digital aeronautical communication system (L-DACS) in the presence of distance measuring equipment (DME) interference. First, we describe the OFDM receiver of the LDACS1. In addition, we discuss the impacts of the DME spectrum on the subcarrier...

Secure and Efficient IP Mobility Support for Aeronautical Communications

Efficient Spectrum Sensing for Aeronautical LDACS Using Low-Power Correlators

Air traffic has seen tremendous growth over the last decade pushing the need for enhanced air traffic management schemes. 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. Cognitive radio based approaches have also been proposed for LDACS...

Mobile Ad-Hoc Network Based Relaying Data System for Oceanic Flight Routes in Aeronautical Communications

This paper proposes a reliable system to overcome the weakness of current the HF radio communication system for oceanic aeronautical flight routes. This system uses only one aeronautical VHF channel with air-toair radio relay system based on local mobile Ad-hoc networks. For access to/from all aircrafts in the system, a TDMA (Time Division Multiple Access) scheme is proposed to be used where ea...

The SANDRA Communications Concept - Integration of Radios

The Single European Sky Air Traffic Management (ATM) research programme SESAR has identified continued growth in demand for aircraft communications as air traffic increases and communications become more network centric. Alongside existing systems such as VHF Data Link Mode 2, new systems such as the L-band Digital Aeronautical Communication System (LDACS) and the Aeronautical Mobile Airport Co...
