\begin{abstract}
In today's wireless communication, it is important to know how signals change on their way to the receiver. There are many different ways how this can happen. This paper will be focused on the study of the \emph{multipath fading effect}. The aim is to easily illustrate the change of the signal evoked through this effect.
First some basic fundamentals are discussed, followed by the implementation in as simulation of those different models, including the transmitter and receiver chain. Later implemented with the help of two SDRs.
The effect is finally shown with the help of a GUI.
