摘要
研究了一类向量小波系统{tl,j1/2Ψl(tlj·-kbl):1≤l≤r,j,k∈Z}.对{Ψl}1≤l≤r, {tl,j}1≤l≤r,j∈Z及{bl}1≤l≤r施加一定的条件,这类小波系统生成L2(R)的标架.
In this paper, a discrete multi-generated wavelet systems {tl.j^1/2ψl（tlj·-kb1）：1≤l≤r,j,k∈Z} is studied. It shows that for certain {ψ}1≤l≤r,{tl,j}1≤l≤r,j∈z, and {bl}l≤l≤r the wavelet system is a frame on L^2 （R）
