Research on Pseudo Sparse-Sequences
Hu Yu · Dianzi xuebao · 2002
Pseudo sparse sequence has wide applications in information hiding technology.This paper presents several classes of pseudo sparse sequences,named respectively product sequences,self shrinking product sequences,self expanding sequences,sparse sequences based on GF(2 m) ,and sparse sequences based on power residue symbol.Their randomness is discussed,mainly on the least periods and linear complexities.
