COMPLEX SPREADING SEQUENCES WITH A WIDE-RANGE OF CORRELATION-PROPERTIES

This paper presents a new family of complex valued pseudo-random seque nces for use in coded multiple access communication systems, The famil y offers a very wide range of values for both auto-correlation (AC) an d cross correlation (CC) functions, allowing great flexibility in the selection of characteristics of sequence sets. Based on the measure de scribed in this paper for the mean-square aperiodic AC and CC values o f a set of sequences, the correlation properties of sets of these sequ ences are compared to well-known sequence sets, and it is shown that S ets from the new family of sequences have superior qualities, Tables o f parameters for various sequence sets are presented to enable the con struction and comparison of sets from this new family.
