摘 要: 利用高维非平稳子分法的极限函数构造一组C∞c (Rd)的尺度函数φj(x) (j 0), 进而构造出高维非平稳Semi多分辨率分析{Vj}j 0 , 证明了该组非平稳Semi多分辨率分析在一定条件下可生成非平稳标准正交Semi MRA, 且该条件是必要的. A multi-dimensional nonstationary orthonormal semi-multiresolution algorithm was constructed. The limit functions of a multidimensional nonstationary subdivision algorithm were used to create a series of scaling functions φ_j(x)(j0) in space C~∞_c(R^d). Subsequently, multi-dimensional Semi-MRA {V_j}_(j0) was built using these scaling functions. This nonstationary Semi-MRA generated a nonstationary orthonormal Semi-MRA under certain conditions. These conditions are specified.
