Abstract

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.

混合伽马衰落与错位条件下的室外太赫兹链路性能分析

精确的链路级理论性能分析对于新兴的无线通信系统至关重要。我们对室外点对点太赫兹（THz）链路进行了详细研究，并纳入了混合伽马（MG）小尺度衰减和错位效应。得出了误码率、中断概率和遍历容量的闭式表达式。此外，我们还对高信噪比进行了渐近分析，强调了收敛条件。利用基于测量的信道参数得出的仿真结果验证了各种配置下的分析结果。

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.
