| 摘 要： | 为了产生性能良好的伪噪声（PN）序列，基于一个新的超混沌系统，文中提出了一种超混沌PN序列的设计与实现方法，在对连续超混沌系统离散、量化的基础上，利用FPGA芯片实现了这种超混沌PN序列。通过一个串口通信模块电路采集了输出序列的全部样本并进行了序列性能分析，分析表明这种超混沌PN序列具有优良的随机特性和自相关特性，可用于扩频通信和信息加密之中。

| Abstract: | In order to generate good PN sequence, the method for designing and implementing hyperchaotic PN sequence based on a new hyperchaotic system is proposed. On the basis of dispersing and quantifying the continuous hyperchaotic system, a FPGA chip is utilized to implement the hyperchaotic PN sequence. The total output sequence samples are collected via a serial-port communication module, and then tested by a series of performance analysis. The analysis shows that this kind of hyperchaotic PN sequence has good properties on randomness and auto-correlation properties. The hyperchaotic sequence, therefore,cou]d be applied in spread spectrum communication and information encryption. |
