摘　　要：研究了GMSK调制方式在跳频通信应用,结合跳频通信中常见VHF跳频电台的工作模式,在Simulink下模拟仿真了基于FH-GMSK调制的VHF跳频电台发射和接收模块,给出了在不同信噪比下的误码率;研究了VHF跳频电台存在的敌意干扰,包括跟踪干扰和阻塞干扰,建立了上述干扰的模型,并在Simulink下构建了干扰模块,同时给出了相关的仿真频谱图,为进一步研究干扰识别中频谱特征提取打下了基础。In this paper, on the basis of applications of GMSK modulation in frequency--hopping communication, combined the working mode of VHF frequency--hopping radio, the transmitter and receiver modules based on the FH--GMSK are simulated by the Simulink, the error rate under the different signal to noise ratio is given; the enmity jamming of VHF frequency--hopping radio is studied, including the follower jamming and barrage jamming. The model of the jamming is built and the jamming module is simulated by the Simulink, and the fre quency spectrums of jamming are given. In the further research, its can provide a basis for the spectral feature extraction in jamming identification.
