AI 中文摘要
实验研究表明，太赫兹链路能够支持多公里级、吉比特每秒的无线传输。然而，很少有研究通过高容量、长距离的实验来有效验证信道模型。在这项工作中，我们实验演示了一个30公里超长距离光子太赫兹无线通信系统。传输并测试了16 Gbaud正交相移键控（QPSK）信号，实现了30 Gbps的最大数据速率。我们首次利用完全实现的30公里实验装置验证了两种广泛使用的太赫兹信道模型，提供了将理论建模与实验结果相结合的系统而全面的分析。我们还对光子太赫兹通信系统的功耗进行了分析，并提供了模拟与实验功耗结果的详细比较。最后，提供了模拟与实验结果之间的详细性能比较，包括信噪比（SNR）、误码率（BER）和数据速率。我们的工作为未来高容量太赫兹网络的设计和节能部署提供了重要见解，为信道建模、实验验证和系统级能效方面的后续研究建立了基准。
英文摘要
Experimental studies have demonstrated that THz links can support multi-kilometer, gigabit-per-second wireless transmission. However, few studies have effectively validated channel models through high-capacity, long-distance experiments. In this work, we experimentally demonstrate a 30 km ultra-long-haul photonic THz wireless communication system. 16 Gbaud quadrature phase shift keying (QPSK) signals are transmitted and tested, achieving a maximum data rate of 30 Gbps. For the first time, we validate two widely used THz channel models using a fully implemented 30 km experimental setup, providing a systematic and thorough analysis that integrates theoretical modeling with experimental results. We also perform an analysis of power consumption in photonic THz communication systems and provide a detailed comparison between simulated and experimental power consumption results. Finally, a detailed performance comparison between the simulation and experimental results, including signal-to-noise ratio (SNR), bit error rate (BER) and data rate, are provided. Our work provides essential insights for the design and energy-efficient deployment of future high-capacity THz networks, establishing a benchmark for subsequent research in channel modeling, experimental verification, and system-level energy efficiency.
