Full-length non-linear binary sequences with Zero Correlation Zone for multiuser communications

Mahdiyar Sarayloo, Ennio Gambi, Susanna Spinsante

Abstract


The research on new sets of sequences to be used as
spreading codes in multiple user communications is still an active
area, despite the great amount of literature available since many
years on this topic. In fact, new paradigms like dense and
decentralized wireless networks, where there is no central
controller to assign the resources to the nodes, are revamping the
interest on large sets of sequences providing adequate correlation
properties to support a big number of nodes, in potentially hostile
channels. This paper focuses on the Zero Correlation Zone (ZCZ)
property exhibited by a family of non-linear binary sequences
featuring a great cardinality of their set and good securityrelated
features, and provides evidence of their suitability to
multiuser communications, in channels affected by multipath.
