摘要
This paper characterizes all generalized low pass filters and MRA Parseval frame wavelets in L-2(R-n) with matrix dilations of the form (Df)(x) = root 2f (Ax), where A is an arbitrary expanding n x n matrix with integer coefficients, such that vertical bar detA vertical bar = 2. The pseudo-scaling functions, generalized low pass filters and MRA Parseval frame wavelets are studied and some important properties about them are given.
