Abstract: This article discusses the technology of simulation in Spread Spectrum (SS) Communication experiment. The system simulation thought of Matalab Simulink is used to realize the simulation of direct sequence spread spectrum(DS-SS)communication experiment. Besides, it compares and analyses the error-ratio under different spread plus in this system. This is also a beneficial trail in teaching on the Web, the branch of long-distance teaching platform.
