Simulation Research of SSB Modulation and Demodulation Based on SystemView

Based on the SystemView simulation platform,with the analysis of the basic principle of single sideband modulation and demodulation,this paper uses phase shift method to realize lower side band modulation,and uses coherent method to implement the demodulation.We study the single sideband system simulation realization based on SystemView software environment,design the corresponding system simulation model,set its parameters,add noise sources to the module to imitate noises in real channel.Finally,simulation results are analyzed.The characteristic of SSB communication that has narrow bandwidth occupied is demostrated by applying the analysis windows to the spectral analysis of the demodulated signal.Therefore,system simulation with SystemView is feasible and effective.
