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.)

将信号映射到小波域，根据噪声和噪声的小波系数在不同尺度上具有不同的性质和机理，对含噪信号的小波系数进行处理。实质是减少剔除噪声产生的小波系数，最大限度的保留真实信号的系数。 (Will be mapped to the signal wavelet domain, according to noise and noise of wavelet coefficients in different scales with different properties and mechanism of signal with noise of wavelet coefficients for processing.Essence is to reduce the noise out of wavelet coefficients, the maximum keep the coefficient of true signals. )

以某些特殊函数为基将数据过程或数据系列变换为级数系列以发现它的类似频谱的特征，从而实现数据处理。(In some particular function or process the data base is converted into data series series series to discover its characteristics similar to the spectrum, to achieve data processing.)
