一种最优的紧框构造算法

Custom Building Finite Tight Frames

设{φm}M m=1是C^N中一组不全为零的向量,本文提出了一种通过增添N-d_1个向量使其构成C^N的一个紧框的最优算法,其中d_1由{φm}M m=1确定。

Let {φM}^Mm=1be not all zeros vectors of CN. This paper introduced an M algorithm to construct a tight finite frame by adding N - d1 vectors to {φM}^Mm=1, where d1 is determined by {φM}^Mm=1.
