On the basis of the analysis of the spread spectrum communication system and the compile principle of turbo codes,Simulink block library of MATLAB software are used to build the spread spectrum communication system simulation model based on turbo codes.The time profile and the error rate of the transmitted information sequence are emulated under certain simulation conditions.Simulation results show: while there is no noise,the receiver can accurately recover the received information sequence;while there are noises,the recovered information sequence has the lower error rate,which shows the spread spectrum communication system based on turbo codes has the good effect of noise suppression and achieves the desired purpose.
