Aerial Base Station Assisted Cellular Communication: Performance and Trade-Off

The use of Aerial Base Stations (ABSs) has received a great deal attention in academia and industry as means to support the cellular communication traffic growth. In this article, we focus on obtaining optimal altitude an ABS using two criteria - maximum cell coverage area minimum Symbol Error Rate (SER). Our study is done by probabilistic air-to-ground channel model, developed for low aerial platforms via simulations commercial ray tracing software, different scenarios like Urban High Rise, Urban, Suburban. probability distributions power ground users delay profile at are provided function size area. For SER analysis, present system model based Generalized Frequency Division Multiplexing (GFDM), time-frequency grid that compatible with Long Term Evolution, implementing parameters latency physical layer. impact “Better than Nyquist” pulses GFDM evaluated terms performance. From presented results, significant improvement demonstrated compared traditional Nyquist pulses.
