Application of AOFDM on Simulated Test Flight Scenario

Abstract

This paper presents the test results of an Adaptive Orthogonal Frequency Division Multiplexing (AOFDM) modulation system on virtual flight path scenario of a Link Dependent Adaptive Radio system. This work also compares its results with fixed rate OFDM with the same Signal to Noise Ratio (SNR). The AOFDM system identifies the distortion of the individual OFDM tones and adjusts the modulation to optimize the performance of each tone. Such a design demonstrates significant improvement of spectrum efficiency and error performance for different test flight scenarios.
