Abstract: The simulation of Direct Sequence/Frequency Hopping Spread Spectrum is discussed by a lot of researches; on the other hand a few researches illustrated the hybrid spread spectrum including Direct Sequence/Frequency Hopping/Time Hopping. In this study, a complete simulation in addition to a mathematical analysis of a coded hybrid Direct Sequence/Frequency Hopping/Time Hopping Spread Spectrum transmitter system is presented. The simulation is performed by using the matlab Graphical User Interface that shows the effect of changing multi values of the system parameters on the transmitted signal.
