\begin{abstract}
Today wireless devices are omnipresent and have to work under technically adverse circumstances. Among the multitude of problems affecting wireless communication systems, a common issue is what is known as the \emph{multipath fading effect}. The aim of this work is to create a demonstrative platform that can illustrate how multipath fading degrades a wireless communication link. A number of scenarios affected by multipath fading were elaborated, simulated and measured using two USRP B210 software defined radios and the GNU Radio signal processing toolkit. To demonstrate the effects, a custom graphical front-end for GNU Radio was built using the Dear IMGUI framework.
