Performance Evaluation of Spreading Codes with Negative Auto-Correlation Based on M-sequences and Chaos Theory
Shohei Tokunaga, Akio Tsuneda (Kumamoto Univ.) CAS2012-66
Abstract (in Japanese) (See Japanese page) 
(in English) Spreading codes with appropriate negative auto-correlation can reduce average multiple access interference (MAI) in asynchronous DS/CDMA systems compared with the conventional M-sequences and Gold sequences generated by linear feedback shift registers (LFSRs).
We design spreading codes with negative auto-correlation based on M-sequences and the chaos theory for the Bernoulli map.
We evaluate periodic auto-correlation properties of the proposed codes.
Furthermore, we evaluate BER performances of asynchronous DS/CDMA systems using the proposed codes by computer simulations.
