Based on the deep study of the concept of 3D DTM (tree dimensional digital topographic map), the author further discussed the technology and core theories of 3D digital topographic map. 3D digital topographic map is actually the 3D spatial data display and visualization based on abstract symbol, it is vector map, in which relief, features and their cubic(More)
It is well known that a finite abelian group can be written as a direct product of p-groups. Therefor the problem of counting the fuzzy subgroups of finite abelian groups must be first solved for p-groups. In this paper, we determine the number of fuzzy subgroups of finite abelian p-groups with type (p<sup>n</sup>, p<sup>m</sup>), and get explicit formula(More)
—In order to solve the inevitable data collision in competitive datalink random access of wireless sensors networking, this paper provides a blind property restoral maximum likelihood (ML) approach for demodulating multiple co-channel digital signals received synchronously at an antenna array. The finite alphabet property of digital signal combining with ML(More)
