摘要
从空间V0 的框架出发 ,找出该空间的尺度函数 ,把框架转化成Riesz基 ,从而做框架下的不规则采样定理就转化为在Riesz基下做不规则的采样定理 ,或者说Riesz基下的不规则采样定理在一定的条件下可推广到框架下去。该定理可用于数字信号处理领域。
From the space V 0 , the scaling function of it is found. It is possible to transform the frame of V 0 into Riesz base of it (of course, the orthogonal bases are also Riesz bases),so that the irregular sampling theorem on the frame is changed into the one on the Riesz bases, in other words, the irregular sampling theorem on the Riesz bases is extend onto the frame. The irregular theorem on the frame can be used to the signal process.
