摘要

我们提供了一个自适应传输技术容量的分析框架，同时考虑了广义衰落信道和高斯分布收发器硬件损伤（THI）。给出了最优功率和速率自适应能力、恒功率最优速率自适应能力、固定速率信道反转能力和固定速率截断信道反转能力的精确表达式。这些表达式很通用，足以涵盖广泛的无线信道。由于高数据速率太赫兹（THz）通信对THI的高敏感性，我们应用我们的结果来研究太赫兹通信系统的容量，并通过数值模拟证实了我们方法的有效性。

Capacity of Wireless Channels Under Transceiver Hardware Impairments and Adaptive Transmission Techniques

We provide an analytic framework for the capacity of adaptive transmission techniques, taking into account both generalized fading channels and Gaussian-distributed transceiver hardware impairments (THI). We derive exact expressions for the capacity of optimal power and rate adaptation, optimal rate adaptation with constant power, channel inversion with fixed rate, and truncated channel inversion with fixed rate. These expressions are general enough to cover a wide range of wireless channels. Due to the high susceptibility of high-data-rate terahertz (THz) communications to THI, we apply our results to investigate the capacity of THz communication systems and confirm the validity of our approach using numerical simulations.

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.
