在MATLAB环境下，以上代码通过编译。P0311：利用巴特沃斯（Butterworth）低通滤波器对受噪声干扰的图像进行平滑处理 P0312：利用巴特沃斯（Butterworth）高通滤波器对图像进行锐化处理(In the MATLAB environment, the above code through the compiler. P0311: the use of Butterworth (Butterworth) low pass filter on the image noise by smoothing treatment P0312: the use of Butterworth (Butterworth) high-pass filter for sharpening images treatment)

Modulation and demodulation ASK. At the beginning, we create the digital signa (1 and 0), after we do the modulation, add noise and demodulation. At the end we do the reconstruction of the signal.
