Abstract

In this letter, we evaluate the impact of beam misalignment (BM) fading on Terahertz (THz) drone communications by deriving simple novel closed-form expressions for the outage probability and average bit error rate (BER). Additionally, we present a high signal-to-noise ratio (SNR) regime analysis, resulting in the diversity orders of the outage probability and the average BER under the BM fading, including their asymptotic limits as a function of distance. We show that the results via our proposed closed-form expressions depict good agreement with the results via simulations and alternative expressions from the literature, also highlighting the simplicity of our solutions, which leads to valuable insights via diversity order analysis.
