INTRODUCTION High speed data communications between civil aviation aircrafts and terrestrial networks can be achieved by broadband aeronautical communication data links, which play important roles in the future air traffic management (ATM), as well as providing communications services for flight passengers (e.g., Internet and cell-phones).
Particularly, International Civil Aviation Organization has authorized the European Organization for the Safety of Air Navigation (EUROCONTROL) to fund projects for developing new air-ground data-links over L-band, namely the L-band Digital Aeronautical Communication System (L-DACS).
