| Abstract(in English) | The sigma-delta cellular neural network (SD-CNN) is a novel framework of spatial domain sigma-delta modulation utilizing neuro dynamics. Also, it has signal reconstruction and noise shaping characteristics that are important sigma-delta properties. Although the noise shaping effect with the oversampling technique plays very important role for drastic quantization noise reduction in binary digital sequences, the conventional SD-CNN could not use it effectively due to the fact that an oversampling factor of the SD-CNN has been undissolved mathematically. In this paper, a novel SD-CNN with the oversampling technique having second order noise shaping property by multi-stage noise shaping (MASH) is proposed. Moreover, the oversampling factor of SD-CNN is demonstrated mathematically. Experimental results of various standard test images in several oversampling ratios suggest that the proposed oversampling SD-CNN has an excellent AD and DA performance. |
