摘 要: 把图形处理技术和数字通讯理论相结合,提出图形解调算法,并以差分去均值图形调相为例,说明该算法具有较高的解调增益,以及不需频率跟踪、相位跟踪和自提取位同步等特点. This paper proposes a new graphic method of demodulation by combining the technique of image processing with the theory of the data communication, which is proved to be of higher gain and the characteristics not to need frequency track and phase track, and can extract the bite synchronization by itself.
