Abstract: In digital communication, in order to reduce the influence of non-linear factors and bandwidth limitation in the channel, the minimum frequency shift keying (MSK) digital modulation technology is deeply discussed, and the simulation circuit diagram of MSK system is designed based on System View simulation platform, and the dynamic simulation and result analysis of MSK system are carried out. The simulation results show that MSK can not only keep the modulated phase continuous to reduce side lobes, but also keep the envelope constant. It has the advantages of narrow bandwidth, concentrated spectrum main lobe energy, fast sidelobe roll-down attenuation and high bandwidth utilization.
