抑制载波双边带调幅和解调的实现,

Matlab代码编写实现.

采用Matlab或者其它软件工具实现对信号进行抑制载波双边带调幅（DSB-SC）和解调，并且绘制：

（1）信号 及其频谱；

（2）载波 ；

（3）DSB-SC调制信号及其频谱；

（4）DSB-SC调制信号的功率谱密度；

（5）相干解调后的信号波形。

-Carrier suppression bilateral with the realization of amplitude modulation and demodulation, Matlab code prepared to achieve. Using Matlab or other software tools to achieve suppression of signals with carrier bilateral AM (DSB-SC) and demodulation, and mapping: (1) signal and its spectrum　( 2) Carrier　(3) DSB-SC modulated signal and its spectrum　(4) DSB-SC modulation signal power spectral density　(5) coherent demodulation signal waveform.
