A countable collection X of functions in L2(IR ) is said to be a Bessel system if the associated analysis operator T ∗ X : L2(IR ) → `2(X) : f 7→ (〈f, x〉)x∈X is well-defined and bounded. A Bessel system is a fundamental frame if T ∗ X is injective and its range is closed. This paper considers the above two properties for a generalized shift-invariant system X. By definition, such a system has t...

This paper presents generators based on decimated sequences of Generalized Feedback Shift Register (GFSR) generators. The equivalence relation between decimated GFSR generators and Tausworthe generators are presented and a k-distributed initialization scheme is derived. We present decimated GFSR generators that are maximally equidistributed. Timing results of these generators are presented.
