Abstract :
In this paper, new polyphase sequences and a sequence generation method are suggested. The correlation properties of the sequences are investigated. These sequences have good correlation properties. Since the suggested generation method consists only of integer sums and modular techniques, sequence generation is also easy. The performance of the sequences is investigated for QS-CDMA systems in frequency selective, time nonselective, slow Nakagami fading channel with additive white Gaussian noise.
