Complex pseudo random spreading sequences with a wide range of correlation properties
Ian Oppermann, Branka S. Vucetic · 2002
This paper introduces a new family of complex valued pseudo random sequences, for use in coded multiple access communication systems. The sequences offer a very wide range of correlation properties. Based on a measure described, the correlation properties of sets of these sequences are compared to well known sequence sets and it is shown that the new family of sequences has superior qualities. Lower bounds on the aperiodic autocorrelation (AC) and aperiodic cross-correlation (CC) values for sequences of this family are introduced and it is shown that sequence subsets exist in which the average correlation values approach these bounds.
