摘　　要：为了获得性能良好,适于扩频通信及加密领域的伪噪声(PN)序列,提出了一种PN序列量化产生及硬件实现方法。该方法基于FPGA技术并以Logistic离散映射作为随机信号源,提取Logistic映射时间序列二进制数中的某一位构成了一个新的混沌PN序列,并在硬件上获得了实现。通过对序列的频率测试、串列测试、Poker测试、游程测试、自相关测试表明,这种PN序列的硬件实现技术可为扩频通信和信息加密提供一个良好的伪噪声序列。In order to obtain a Pseudo Noise（PN） sequence which is good in performance,in spread spectrum communication and encryption. A generating and hardware realizing method of a type of PN sequence is proposed. This method utilizes FPGA technology and adopts Logistic mapping as the random signal source, then a certain bit in the binary number, which is the output time series of the Logistic mapping,it is extracted to make a new chaotic PN sequence,then the hardware implementation is obtained. The tests including frequency test, serial test,Poker test, runs test and autocorrelation test show that the hardware implementation technology of this kind of PN sequence provides a good PN sequence for spread spectrum communication and information encryption.
