采用频率调制 为1000Ｈｚ的载波，在解调前把加性白高斯噪声加入到调制信号。当噪声功率和调制信号功率比为０.００１，０.０１，０.０５，０.１和０.３是进行解调并绘出调制信号-The use of frequency modulation for the 1000Hz carrier, in the demodulation before AWGN added to the modulation signal. When the noi

频率调制，属于角度调制中主要一种，相位调制可以通过对信号先微分再调频获得-Frequency modulation, angle modulation in the main belong to a kind of phase modulation of the signal can be differential access to re-FM
