| 摘 要： | 直序扩频通信系统中,扩频序列的各项性能指标直接影响到通信系统的扩频增益、抗干扰性能以及多用户复用性能等。混沌序列具有良好的相关性、可重生性等特性,可作为理想的直序扩频码应用于低压电力线通信中。对混沌扩频技术在电力线通信中的应用进行了探讨,提出了一种利用Logistic映射得到大量适用于直序扩频系统的混沌扩频序列的算法,并在Matlab环境下编程实现了该算法。在此基础上分析了所得混沌序列的性能并与M序列、Gold序列加以比较,证明了算法的可行性。

| Abstract: | The spread spectrum sequences's performance directly affects the DS - SS communication system's processing gain,anti - disturbance capacity and multi - user accessibility. Chaotic sequences,which have good correlation and re - generation performance, can be applied in the low voltage powerline communication as an excenllent alternative. The paper investigates the chaotic SSC applied in the PLC, proposes a method for generating numerous chaotic sequences suitable for use in DS/SS system , analyzes the statistical characteristic of result of the algorithm by program in the mallab background and testifies the feasibility of the algorithm by cmparing the capabilities of the M code and Gold code. |
