基于已知的一维混沌映射伯努利映射和帐篷映射，设计了具有时滞负自相关的扩频序列。我们还证明了基于这种有限位映射的具有负自相关的最大周期二进制序列可以由一类非线性反馈移位寄存器（NFSRs）生成。此外，我们使用这种负自相关扩频序列进行了异步DS/CDMA通信的计算机模拟。
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.
