| 摘要: |
| 在各种混沌映射的基础上,为了改善混沌序列被截短带来的影响,提出了一种级联型的混沌映射。研究和仿真证明,该方法产生的混沌序列在伪随机性、相关性、平衡性、误码率方面的性能优良,很适合用于DS/CDMA扩频通信中。 |

|
| () |
| Abstract: |
| To improve the effect from the cut of chaotic sequences,this paper proposes a serial chaotic sequence on the base of various of chaotic maps.Research and simulation show that the properties of the sequence in PN,correlation,balance and BER are good,so it can be used as sprend spectrum(SS) sequence in DS/CDMA communication systems. |
| Key words: CDMA,sprend spectrum system,chaotic sequence,PN,relativity |
