Comparison of performance between chaotic sequences and nonlinear sequences based on shift register

摘要

摘要: 混沌序列与一类基于移位寄存器的非线性序列非线性前馈逻辑(Non-Linear Feed-ForwardLogic，NLFFL)序列都具有非线性、宽带类噪声、大的码族、长的周期且容易产生的特性，通过对它们在产生方式、相关性能、多址性能以及抗相关攻击能力等方面进行分析和仿真研究，说明混沌序列与该类非线性序列在性能上总体相当，但对于短周期序列(N1023)，混沌序列的抗相关攻击、抗干扰能力更强，因此更具有实用价值。

Abstract: Both chaotic sequences and nonlinear feed-forward logic (NLFFL) sequences based on linear shift register almost have the same properties: the ease of their generation and various families with a large family size and long sequence period, as well as their broadband noise-like and non-linear nature. Their generation methods, correlation properties, Code Division Multi-ple Access (CDMA) properties and their resistance against correlation attack are compared in the paper. By simulation, it shows that most of their properties are comparable, but chaotic sequences are less vulnerable to correlation attack and jamming than some NLFFL sequences when their period is less than or equal to 1023, so they have more practical value than these nonlinear sequences based on shift register.
