Abstract :
In this paper, the physical layer design of the B-VHF system is described and discussed. B-VHF is a broadband communications system for air-traffic control based on multi-carrier technology which is intended to be applied as an overlay system to the existing aeronautical communications systems in the VHF band. Special focus in this paper is put on the physical layer design challenges which have to be solved in order to guarantee the co-existence between B-VHF and the legacy VHF systems. Especially, the interference avoidance techniques at the B-VHF transmitter as well as the required interference suppression techniques at the B-VHF receiver are discussed in detail.
