A new family of quadriphase sequences for CDMA
Tomás̆ Novosad · IEEE Transactions on Information Theory · 1993
The construction of a family of quadriphase sequences that are suitable for code-division multiple-access spread spectrum (CMA/SS) communication is described. For a given parameter n, where n=2(mod 4), the period of the sequence is 2/sup n/-1 chips. The set of sequences asymptotically achieves Welch's lower bound on simultaneous cross-correlation and autocorrelation magnitudes, all of them being bounded by a value 2/sup n/2/+1. The cardinality of this family of sequencies is 2/sup n/2/.>
