\section{Introduction}

For the semester thesis at the Eastern Switzerland University of Applied Sciences (OST) it has been requested to create a demonstrative setup to show the fading effect, which is present in real world wireless communication systems.
The device is intended to be used for pedagogical purposes such as to show the effect at the Open Days or for demonstrations during future lectures on fading channels.

\section{Task Description}

The scope of the project is to realize a demonstration of a fading channel using a software defined radio (SDR).
Out of the many types of fading effects that exist only small scale fading effects ought to be shown in the demonstration, specifically multi path propagation fading is of interest.
The project requirements that must be fulfilled are thus:
\begin{itemize}
	\item Understand of one or more mathematical models of the fading effect.
	\item Evaluate a suitable development environment for the SDR.
	\item Develop of a signal processing chain for the SDR transmitter and receiver.
	\item Develop of an interface to vary the parameter of the transmission, such as the modulation scheme.
	\item The demonstration should work with both stationary and moving receivers.
\end{itemize}

\section{Development plan}

The development of the project will be carried out roughly in three phases, of which the first two will start in parallel.
\begin{enumerate}
	\item Develop an understanding of fading and how to work with SDR devices.
	\item Create a basic TX -- RX line \emph{without} a fading channel model.
	\item Integrate the fading channel model into the prototype.
\end{enumerate}

\subsection{SDR Device}
Finding the right software tool, like GNURadio or Matlab, for the Project and learn how the program works. The same with the Hardware, is the \textit{USRP B210} the best option or is there an other SDR, which fits better too our requirements. 

\subsection{Prototype}
Create the first Prototype line TX-RX without any effects. Including some simulation on that setup first and then tests and measurements on the Hardware. 
After a successful set up, some possible variable parameters will be included. 

\subsection{Theory of fading channels}
When the Prototype works the integration of the fading channel models starts, including simulations and tests on the Hardware. 
At the end comes the same with a movable Reviser. Walking will be used to demonstrate that on a scenario. If there will be some time left also with the help of a car.
