The simulation design of communication system based on LabVIEW

The principles of several analog modulation system and digital modulation system which are commonly used in the communication system were analyzed, and the simulations of several common communication systems were realized in LabVIEW 8.6 software platform in this paper. The results of simulation show that the interface of each system is beautiful, the parameters are easy to adjust and the process of modulation-demodulation is simpler than the traditional system which is designed by hardware circuit. The realization of the system can be used for engineering design and scientific experiment.
