Abstract :
The digital part of UWB system is replaced by a new one, which is more robust and provide an immense improvement of the system output data rate. The impact of the new sampling module on the system is being discussed. The effect of the clock jitter and drift on the system performance is also addressed, since jitter and drift is our biggest problem right now. System was operated for two times with time separation to test the system stability and repeatability over time.
