 \chapter{Conclusions} \label{chp:conclusions}
 
-The goal to build a functional demonstrator could be realized, unfortunately not with all futures as originally planned. A functional receiver and transmitter chain, for QPSK were implemented,
-but the 16-QAM dosent work as hoped.
+\section{Results}
+
+The goal to build a functional demonstrator had been achieved, unfortunately not all of the originally planned features were implemented. A stable wireless link using QPSK modulation that computes the BER was developed.
+
 Some different typ of multiple fading model were tested and illustrated.
-Two different Models for the simulation options are build. One discrete time model whish is basicly a FIR filter in the channel, the other with a statistical model which is based on a GR block.
-And another file to implement the hardware with. Unfortunately it wasent possible to measure those models in a meaningful way. For that a least square approximation could be used as described in the further steps. An other difficulty is to reproduce the same effect in a simulation compare with the hardware, because of al the side effect of an environment, which cant be predicted in a simulation.

+\section{Future Work}
+
+\subsection{Improve BER measurements and simulations}
+
+An interesting continuation of the current work could be to automate the collection of the BER data, and to measure and observe the influence of each parameters in the fading channel model. In addition, new flow graphs for further modulation schemes could be easily added to the current framework.
+
+\subsection{Improvements of GUI frontend}
+
+The current GUI prototype built with DearPyGUI has some issues, the most critical begin a single-threaded application. The interprocess communication (with GR's flow graphs) should be on a separate thread from the graphics. The problem is not noticeable as long as the flow graphs in the background keep sending data, but as soon as the UDP/IP data stream stops the timeout of the socket interface causes the interface to run at less that 20 frames per second.
 
+In addition to fixing the aforementioned issue, a very important missing feature that is currently missing is the ability to change the fading parameters in real time from within the GUI. Dear PyGUI offers many graphical elements that could be used to control the parameters, however a new GR block would need to be created to propagate the updated values into the flow graph.
 
+\subsection{Channel parameters estimation with Pilot Symbols}
 
 
-\section{Further Steps}
 
-To improve this project a simulation environment could be implementer, which can be replicated for more accurate measurements. So then it is possible to compare the simulation with the measurements.
+\section{Closing words}
 
-An other  developnet basde on this project could be to show the BER with the help of a least Square approximation.(like in the paper)
