Abstract
Spreading sequences with a negative auto-correlation for time-delay one are designed based on the Bernoulli and tent maps which are well-known one-dimensional chaotic maps. We also show that maximal-period binary sequences with negative auto-correlation based on such maps with finite bits can be generated by a class of nonlinear feedback shift registers (NFSRs). Furthermore, we perform computer simulations of asynchronous DS/CDMA communications using such negatively auto-correlated spreading sequences.
