Comparative Analysis of Studies on Performance Improvement Techniques for Aeronautical Channels

Abstract

This paper provides an in-depth exploration of the potential of Orthogonal Frequency Division Multiplexing (OFDM) in aeronautical telemetry applications, comparing it to the widely used SOQPSK standard. The analysis begins with a direct assessment of their performance on a specific channel configuration. The advantages of OFDM, including enhanced spectral efficiency and error distribution characteristics, are highlighted. The study investigates the suitability of OFDM for aeronautical channels, emphasizing its independence of tones and error distribution. Innovative methodologies such as Link Dependent Adaptive Radio (LDAR) and Diversity Combining are discussed to harness these properties. The study also addresses Peak-to-Average Power Ratio (PAPR) disadvantages and introduces methods for reduction. Overall, this paper offers valuable insights into the capabilities and limitations of OFDM, paving the way for improved wireless communication in aeronautical environments.
