This paper studies the realization of the frequency hopping spread spectrum modulator based on MATLAB platform and provides the principle of frequency hopping spread spectrum modulation. Then the simulink module is used to realize the frequency hopping spread spectrum modulation. The length of spread spectrum code in spread spectrum is 15 and frequency hopping pattern is also obtained by m sequence with length of 15. Through the simulation, the author observes the simulation results. This model can realize frequency hopping spread spectrum modulation. Jump points are 15 and frequency hopping rate is 0.04 s per jump.
