| Summary: | 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. |
