Binary phase shift keying （BPSK） by means of a binary baseband signal carrier two-phase modulation method is one of the important applications of signal processing. In this study, FPGA system fast, flexible and stable, high efficiency, on the basis of inquiry BPSK modulation principle, and FPGA technologies, build a platform, so that the test simulation fas- ter and more convenient. BPSK modulation principle is widely applied to various fields of modern communication, precisely because it plays a key role in the simulation and analysis system, making smart cards, Bluetooth and other related technolo- gies have emerged. By using the simulation tool ModelSim modulation signal simulation, simulation results can be clearly seen in FIG. In this study the principles of user-friendly, simulation debugging section is easy to learn, simple, strong ex- pansion.
