The objective of this research is to build upon the existing 18, 37 and 61 GHz narrowband (CW) systems already developed under the project POSC/EEA-CPS/57481/2004 and other previous internal calls of IT-Coimbra (2009 and 2010), in order to incorporate the intermediate stage (IF) of the swept-time delay cross-correlation channel sounder that was developed and successfully implemented by the authors in 2010 . The integration of the existing IF stage into a highly scalable RF stage would represent an incremental step and also a strategic extension of the RF measurement facilities available at IT, particularly for a multi-frequency measurement system capable of measuring channel impulse response, in addition to the dynamic effects, including Doppler spectra for each individual multipath component, of doubly selective propagation channels. The proposed topology for the channel sounder has the portability to be quickly and easily re-located to various measurement sites, as well as the flexibility to characterise a wide variety of frequencies, e.g. 18, 37 and 61 GHz. This is of significance interest for 5G propagation models development.
