Simulation Study of The Direct Sequence Spread Spectrum Communication Based on Simulink

Based on the spread spectrum theory,the simulation model of the direct sequence spread spectrum(DSSS) communication system is built by using Simulink which is a visible tool of Matlab in this paper,each module design of simulation model is introduced in detail.Under the given simulation condition,the simulation module is run and detected,the result answers for the anticipated effect.Meantime,this paper studies the relationship among the spread spectrum gain and interference tolerance of DSSS communication system,error ratio,SNR of channel by means of the simulation module,which establishes the base for the practical application of its anti-jamming.
