OVERVIEW ON BANDPASS NGD BASED SIGNAL PROPAGATION DELAY SUPPRESSION FOR UAV BASE STATION CELLULAR NETWORK
Résumé
This paper presents a literature review on the propagation delay effect of microwave and millimeter wave (mmW) wireless network. The review study is
focused on the cases of mobile wireless system based unmanned aerial vehicle (UAV) base station (BS) cellular network. The two last decades, the UAVs are exploited in 5G network and internet-of-things (IoT) to improve the performances of information communication technology (ICT). Different potential applications of UAV-BS in the modern urban cities are indicated. The main specifications of UAVs in wireless communication are presented. One of main parameters influencing the UAV-UAV and UAV-BS communication performance is the signal propagation delay issue. A potential future research on the improvement of mobile communication system using UAVs by using negative group delay (NGD) electronic function is reviewed. This unfamiliar NGD function enables to suppress the propagation signal delay.
