| Abstract: | In the paper,the rules about how to choice structural elements are presented,and a AM signal demodulation method by one-dimensional morphological filtering algorithm that can manipulate image rim with high efficiency is proposed.The computer simulation experiment shows that the algorithm which possesses strongly anti-interference ability,can conquer the peak noise,AM signal Envelope interference and white noise.It is adequate for AM signal demodulating.Meanwhile the neatly algorithm runs rapidly with quick ... |
