Characterization of NI-USRP SystemFu, Xubo January 2014 (has links)
Nowadays the rapid developments of wireless communication technologies there are more and more ways to look into the RF measurements and designs in detail such as Universal Software Radio Peripheral(USRP) from LabVIEW, Advance Design System(ADS),etc.Moreover a lack of measurements what compared with different digital modulation schemes is becoming a problem. In this thesis by building the simulations of communication system in NI-USRP system and measuring the results then compare with the different PSK system in order to give a deeper insight of this new software of USRP from LabVIEW. and in the end analyze bit error rate varus signal to noise ratio from the PSK system. To get the characterizations of NI-USRP system the first step is to build multiple simulations such as FM receiver, PSK wireless communication systems. By performing the FM receiver is to analyze the quality of the receiving and baseband FM signal. And from the simulation of different PSK communications through the analysis of the performance of BPSK,QPSK,OQPSK and compared with bit error rate it could give an insight of characterization of NI-USRP system and in the end the conclusions give in which kind of prototype or simulation that suit the best of NI-USRP system.
