基于FPGA的超混沌PN序列产生与性能分析

Hyperchaotic PN Sequence Generation and Performance Analysis Based on FPGA

伪噪声序列广泛应用于扩频通信、数字加密、数字系统测试等领域,对于伪噪声序列产生的研究一直是国内外信息领域的热点。该文提出了一种PN序列量化产生及硬件实现方法。该方法通过在硬件上基于FPGA技术实现并以超混沌连续映射作为随机信号源,提取该映射时间序列二进制数中的某一位构成了一个新的超混沌PN序列。通过对序列的各种FIPS相关指标测试,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等领域提供一个良好的伪噪声序列。

Pseudo-noise sequence is widely used in spread spectrum communications,digital encryption,digital system testing and other areas,the research of pseudo-noise sequence generated is always the hotpot in the field of information at home and abroad.This paper presents a PN sequence quantifying generation and hardware implementation.The method through hardware is based on FPGA technology and takes hyperchaotic continuous map as a random signal source and extracts the binary number of mapping time series composin...
