DME interference analysis in aeronautical LTE networks

Abstract

In the last decade, the aeronautical authorities expressed their need to develop a new aeronautical wireless communication system. The L-band Digital Aeronautical Communication System (L-DACS) is a candidate of the future system and orthogonal frequency-division multiplexing (OFDM) will be sued for it. Meanwhile, the Distance Measuring Equipment (DME) is also working in the aeronautical L-band. In our paper, taking LTE for example which is the prospective technology for aeronautical radio communications, we establish an aeronautical LTE communication link model and study the DME impact on it through analyzing the coexistence scenario between them. This article adopts the Monte-Carlo simulation method to perform the co-existing interference study and results show that how the performance of the aeronautical LTE system is affected. It can be very significant to provide reference for specific aeronautical LTE network deployment in practice and evaluating interferences with other aeronautical radio communication systems.
