Performance Analysis of Two-Way Relaying in mmWave-Based Aerial Links

Two-Way Relaying (TWR) is an efficient relaying technique that doubles the spectral efficiency as compared to the traditional one-way relaying. As such, it has been nominated as a solution to extend the coverage of links operating on the Millimeter Wave (mmWave) band. In this paper, the performance of TWR is investigated for mmWave-based aerial links in which the involved entities are all aerial. Taking into account the orientation fluctuations of the involved aerial entities, the performance is characterized in terms of the outage rate and the bit error rate. Closed form expressions are derived based on the considered performance metrics along with a large set of Monte Carlo simulations results to validate the obtained analytical formulas. Analytical and simulation results address the impact of various factors including the number of antenna elements, the modulation order, the transmission distance, and fluctuation intensity.
