摘要

基于MATLAB平台研究跳频扩频调制器的实现，给出了跳频扩频调制的原理，利用simulink模块实现跳频扩频调制。选择15位的扩频码进行扩频，跳频图案也采用15位的m序列产生。经过仿真，观察仿真结果，该模型能够实现跳频扩频调制，跳频频点数15个，跳频速率为0.04s/跳。%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.
