| Abstract: | This paper introduces the method of creating the real-time communication system quickly based on the virtual instrument of NI USRP and LabVIEW,and builds the DQPSK transceiver by using of the equipment of NI USRP-2930 and LabVIEW platform. The transmission and receiving of the signals are through NI USRP-2930,and all signals were processed by LabVIEW. The simulation results show that a USRP connection with a PC acts as a software-defined radio. The performance of DQPSK transceiver system can be optimized by setting the relevant parameters. This paper also implements the design of DQPSK transceiver,and explores the basic and more advanced theory of signal processing and communication of DQPSK. |
