2.4.1 Propsound (EBITG, UOULU, Nokia)
The Propsound multi-dimensional radio channel sounder is a product of Elektrobit, Finland [PSound].
Propsound has been designed to enable realistic radio channel measurements in both the time and spatial
domains. It is based on the spread spectrum sounding method in the delay domain. The other domains,
including polarization, FDD frequency and the spatial domain, are covered using an advanced timedomain
switching technique. Together with optional super-resolution techniques (based on the SAGE
algorithm), this allows accurate measurements of SISO, SIMO, MIMO, geolocation and multi-user
propagation channels. Some key features of Propsound are presented in Table 2-2.
