Abstract:

Cascade No sequences are a family of sequences which comprise cascade GMW sequences and have optimal correlation properties and large linear span. By studying cascade No sequences and shift sequences, an accelerating iterative algorithm for constructing cascade No sequences is presented. The algorithm adopts iterative method, the cascade No sequences with any period can be constructed quickly by using cascade GMW sequences and shift sequences of the small set of Kasami sequences. It is easy for understanding and implementing.

Key words: shift sequences, cascade Gordon-Mills-Welch(GMW) sequences, cascade No sequences
