【摘要】 广义频分复用(Generalized Frequency Division Multiplex,GFDM)技术作为新的多载波技术,凭借其子载波非正交性、时频资源的灵活性等特点成为研究热点。为了抵抗空空数据链中目标高速移动导致的多普勒频移,首次将GFDM技术引入空空数据链中,对空空数据链下GFDM系统的多普勒进行性能分析,对比特出错概率(Bit Error Ratio,BER)进行性能仿真。结果表明,GFDM技术有对抗多普勒频偏的能力。更多还原

【Abstract】 As a new multi-carrier technology,Generalized Frequency Division Multiplex( GFDM) technology has become a research focus due to its sub-carrier non-orthogonality and flexibility of time-frequency resources. GFDM technology is introduced into the air-to-air data link for the first time in order to resist the Doppler shift caused by the high-speed movement of targets. The performance of Doppler of GFDM system in air-to-air data link is analyzed,and Bit Error Ratio( BER) performance simulation is carried out.The results show that GFDM technology has the ability to resist Doppler frequency offset.更多还原
