修正了由Casazza给出的对任意a,b, {EmbTnag}都不是框架的例子, 再构造了一个正测Cantor集, 使得对于所有可数点列{xn}和{ym}, 集E均不是WH框架集, 并且集E也不是小波框架集.

In this paper, the authors first modifies an example introduced by Casazza that there exists a window function g such that the Gabor system { Emb Tna g } isn＇t a WH- frame for all a,bE It, then the authors constructs a Cantor set with positive measure E which never becomes a frame set for all countable {xn } and...
