基于L频段数字航空通信系统1的F-OFDM波形设计
F-OFDM Waveform Design Based on L-band Digital Aeronautical Communications System 1 (L-DACS1)
摘要
Abstract
With the proliferation of aircraft types and numbers and the incoming of new era of the fifth generation (5 G) mobile communications and Internet of Things(IoT),new challenges such as high safety,large transmission capacity,low latency,strong robustness,high elasticity and synthetic service providing are faced by the next generation aeronautical communications system.In this paper,a waveforms design method of filtered orthogonal frequency division multiplexing (F-OFDM) based on L-band digital aeronautical communications system 1 (L-DACS1) is put forward to cope with these challenges and the possible technology evolution path is prospectively discussed.Firstly,the concept of cognitive radio,non-continuous cartier interference code OFDM and filter is introduced,and then the waveform parameters are dynamically and adaptively configured for different aircraft users.The simulation results show that the proposed system has a low power of out-of-band radiation,good block error rate and high throughput gain.关键词
