This paper presents an agile radio channel sounderbased on the cross-correlation properties of pseudo-noise (PN) random sequences, identified in the literature as a swept time delayed cross-correlation (STDCC) channel sounder, also commonly named as a sliding correlation sounder. This sounder enables the characterisation of highly dynamic doubly selective channels, providing both amplitude and Doppler spectra information for each tap of the power delay profile (PDP). It performs real time measurements of specific radio channels with a high resolution of 1ns for adjacent multipath components (MPC), and a current maximum Doppler spread of ±1kHz. The amplitude measurements given by the sounder, shown as PDPs, have a dynamic range of about 60 dB. The paper also provides detailed information on specific RF measurements at 28 GHz in a factory of the future use case.
