EFFECTS OF AERONAUTICAL CHANNEL DYNAMICS ON THE PERFORMANCE OF LINK DEPENDENT ADAPTIVE RADIO (LDAR)

Abstract

This paper includes aeronautical channel dynamics in the flight simulations of the Link Dependent Adaptive Radio (LDAR) for realistic measurement of the throughput gain with the adaption of the modulation and coding parameters for aeronautical telemetry. Previously, the LDAR flight simulator used a fixed channel for different phases of the flight. This paper shows the performance of LDAR using a dynamic channel created by the customized two ray channel model considering delay spread, Doppler and other channel dynamics. The merger of such dynamic channel simulator with the LDAR flight simulator could help the telemetering community by providing reliable simulation results before test flights.
