Based on binary pseudorandom sequences with period 2m-1
A new construction of column sequence sets with period 2m+1-1 was presented.With these column sequence sets
one can get a new class of binary low-correlation zone(LCZ) sequence sets whose parameters can reach the Tang-Fan-Matsufuji bound.These LCZ sequence sets have larger set size
as a result
they can be used in quasi-synchronous(QS) CDMA systems to support more users.
