太赫兹（THz）频率的通信被认为是无线网络中不久的将来的里程碑，也是第六代（6G）无线系统及以后的关键组成部分。在过去的十年中，在器件技术发展以及太赫兹波传播和信道建模方面取得了重大进展。为了推进THz通信和网络研究，非常有必要开发可编程的软件定义硬件和架构，这些硬件和架构在THz频率下工作，能够处理具有数十到数百GHz带宽的信号，从而充分利用THz频段。本文介绍了一个用于进行100 GHz以上无线实验研究的通用测试台。该平台由100 GHz至1 THz之间三种不同频率的多组模拟前端以及三种不同的数字信号处理后端组成，能够实时处理超过10 GHz的带宽。实现细节和早期的实验结果，以证明平台的能力。
Communication at terahertz (THz) frequencies is envisioned as a near-future landmark in wireless networking and a key component of the sixth generation (6G) wireless systems and beyond. In the last decade, major progress has happened in terms of device technology development as well as THz-wave propagation and channel modeling. In order to advance THz communication and networking research, there is tremendous necessity in developing programmable software-defined hardware and architectures that operate at THz frequencies and are able to process signals with tens to hundreds of GHz of bandwidth, thus making most out of moving to THz band. This paper presents a versatile testbed for conducting wireless experimental research above 100 GHz. The platform consists of multiple sets of analog front-ends at three different frequencies between 100 GHz and 1 THz as well as three different digital signal processing back-ends, able to manipulate more than 10 GHz of bandwidth in real-time. Implementation details and early experimental results to demonstrate the platform capabilities are presented.
