am-dsb
AM、DSB 调制及解调
用matlab产生一个频率为1Hz,功率为1的余弦信源m(t),设载波频率ωc =10 Hz,
m0 = 2 ,试画出:
AM 及DSB 调制信号的时域波形;
采用相干解调后的 AM 及DSB 信号波形;
AM 及DSB 已调信号的功率谱;
调整载波频率及 m0,观察分的AM 的过调与DSB 反相点现象。
在接收端带通后加上窄带高斯噪声,单边功率谱密度0 n = 0.1,重新解调。
(AM, DSB modulation and demodulation
Matlab produce a frequency for 1 Hz, power of 1 cosine source m (t), set the carrier frequency ω c = 10 Hz,
M0 = 2, try drawing out:
