摘要

为了满足日益增长的空中交通对频谱的需求，提出了基于OFDM的l波段(960-1164MHz)空对地数字航空通信系统(LDACS)。现有的基于OFDM的LDACS收发器存在诸多缺陷，因此需要新的灵活高效的LDACS协议。为了满足修订后的LDACS协议的上述要求，我们提出了一种基于可重构滤波OFDM (Ref-OFDM)的lldac。所提出的Ref-OFDM波形使收发器能够动态适应传输带宽(uptp 732K)，具有与现有基于OFDM的LDACS相似的架构，满足了改进协议的上述要求。我们通过各种现实通道条件的模拟比较结果来支持我们的主张。

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

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.
