A new Reconfigurable Filtered-OFDM Based L-Band Digital Aeronautical Communication System for Next Generation Air to Ground Communication

Abstract

To meet the spectrum demand of ever-increasing air traffic, OFDM based L-band (960-1164MHz) Digital Aeronautical Communication System (LDACS) was proposed for air to ground. The drawbacks linked with the existing OFDM based LDACS transceivers leads to the need of new flexible and efficient LDACS protocol. To fulfil the above mentioned requirements of this revised LDACS protocol, we have proposed a reconfigurable filtered OFDM (Ref-OFDM) based LLDACS. The proposed Ref-OFDM waveform enables transceivers to dynamically adapt the transmission bandwidth (uptp 732K) has the similar architecture as existing OFDM based LDACS fulfils the above mentioned requirements of the improved protocol. We support our claims via simulation comparison results for various realistic channel conditions.
