M-sequences suitable for mobile DS-CDMA systems

Based on Galois fields theory and computer simulation this paper describes N/sup 1/2//3 m-sequences having relatively low maximum periodic cross-correlation lower bounded by 3N/sup 1/2/ and upper bounded by 0.01 N approximately, where N is a sequence period. The proposed m-sequences are superior to Gold sequences when a number of large periodic cross-correlation values is important, thus, they may be useful for mobile communications based on asynchronous DS-CDMA systems.
