3. Synchronization of Distributed Units without Access to GPS
University essay from Linköpings universitet/DatorteknikAbstract : Time synchronization between systems having no external reference can be an issue in small wireless node-based systems. In this thesis a transceiver is designed and implemented in two separate systems. Then the timing algorithm of "TwoWay Time Transfer" is then chosen to correct any timing error between the two free running clocks of the systems. READ MORE

4. Wireless system design : NB-IoT downlink simulator
University essay from Uppsala universitet/Signaler och SystemAbstract : The newly defined NB-IoT standard currently lacks a toolkit and simulator. In order to develop algorithms for this new standard there is a need for channels and signals as reference during tests. MATLAB is commonly used for testing LTE signals and therefore the toolkit was developed in this environment. READ MORE
