摘要

本文全面概述了如何校准专为低太赫兹(THz)频率范围设计的相关信道探测仪。本文概述的校准过程包括基本方面,包括校准测量的延迟和信道脉冲响应 (CIR) 的振幅。具体来说,它讨论了在背靠背 (B2B) 校准过程中使用的波导的影响,以及天线和噪底估计的影响。此外,还通过解卷积来增强校准程序,以减轻测量系统本身的影响。具体来说,讨论涉及应用于解卷积信号的窗口技术。最后,还讨论了其他注意事项,如平均、插值、MIMO 配置和高分辨率测量。

Time-Domain Channel Sounder Calibration at Low Terahertz Band
This article provides a comprehensive overview of calibrating a correlation-based channel sounder designed for the low terahertz (THz) frequency range. The calibration process outlined herein encompasses fundamental aspects, including the calibration of the measured delay and amplitude of the channel impulse response (CIR). Specifically, it discusses the influence of the utilized waveguides during a back-to-back (B2B) calibration, as well as the effects of antennas, and noise floor estimation. Furthermore, the calibration procedure is enhanced through deconvolution to mitigate the impact of the measurement system itself. Specifically, the discussion addresses the windowing technique applied to the deconvolved signal. Lastly, additional considerations such as averaging, interpolation, MIMO configurations, and highresolution measurements are discussed.
