The Fraunhofer-Gesellschaft ( currently operates 76 institutes and research institutions throughout Germany and is the world’s leading applied research organization. Around 30 000 employees work with an annual research budget of 2.9 billion euros.


The Fraunhofer IIS in cooperation with the TU Ilmenau set up a testbed to enable the localization of mobile endpoints using the LPWAN standard mioty for application in current research topics like IOT. The localization is based on time difference of arrival measurements (TDoA). This promises high accuracy, but places very high demands on the temporal synchronization of the basestations.Another core component of localization accuracy is precise knowledge of the underlying phase noise in the frontend of the basestations. 


Within the scope of this thesis further knowledge about the underlying phase noise process shall be gained for achieving a higher accuracy of the localization when it comes to compensation of the phase noise.


The results achieved in the thesis are to be presented extensively in a written elaboration. The program source code must be sufficiently commented. The DFG rules for good scientific practice are to be respected in the preparation of the thesis. The execution of the work can be done in English as well as in German language.
