Performance Analysis of Outdoor THz Links Under Mixture Gamma Fading With Misalignment
Accurate link-level theoretical performance analysis is crucial for emerging wireless communication systems. We present a detailed study of outdoor point-to-point terahertz (THz) links, incorporating mixture gamma (MG) small-scale fading and misalignment effects. Closed-form expressions for bit-error probability, outage probability, and ergodic capacity are derived. Furthermore, we conduct an asymptotic analysis at high signal-to-noise ratios, highlighting the convergence conditions. Simulation results, using measurement-based channel parameters, validate the analytical findings across various configurations.
期刊介绍：
The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
