Abstract：Noise frequency modulation(FM)jamming。which belongs to blanket jamming。is already become the main form ofnoise jamming at present。because the wideband was gained by it．Tne spectnlnl ofnoise FM jamming is analyzed by time domain autocorre

GMSK的调制和解套，显示基带信号和解调信号波形及其频谱图-GMSK modulation and some sort of relief, showing a baseband signal and demodulating the signal waveform and its spectrum

对于AMBE的输出信号进行OOK调制，仿真能过，但实测有问题，仅供参考(For the AMBE output signal OOK modulation, the simulation can be over, but the measurement is a problem, for reference only.)
