Abstract: This paper introduces two kinds of sequences used in spread spectrum communication system: pseudo-noise (PN) sequence generated by linear feedback shift register(LFSR), such as m-sequence and Gold sequence, and the chaotic sequence generated by the determination of the nonlinear system. The characteristics of PN sequence and chaotic sequence are analyzed by simulation, and the advantages and disadvantages of different sequences in spread spectrum communication system are obtained. The advantages of sequence can be used to improve signal transmission in a spread spectrum communication system.
Key words: spread spectrum system; chaotic sequence; linear feedback shift register (LSFR) sequence; peseudo-noise (PN) sequence

摘要:本文介绍了在扩频通信系统中应用的两种序列:由线性移位寄存器(LFSR)产生的PN序列, 如m序列和Gold序列; 另一种是由确定的非线性系统产生的混沌序列。 通过仿真分析了PN序列和混沌序列各自的特性, 并由此得出不同的序列在扩频通信系统中的优缺点, 从而利用序列的优点来改善扩频通信系统中的信号传输。
