摘要:

针对置换序列码(PSC)的构造方法,以及对PSC码的自相关和互相关特性的对比,对GF(2m)域满足生成PSC码的本原根进行存在分析,给出了此种本原根的个数下限,提出了生成这种本原根的方法. 将PSC应用于超宽带系统中,仿真结果表明,使用PSC码的超宽带系统的性能明显优于使用其他码型的系统.

关键词: 置换序列码, 有限域, 超宽带, 跳时码

Abstract:

Baed on the way to construct permutation sequence code (PSC) and comparisons of the characteristics of autocorrelation and crosscorrelation, the existence and the low bound of the primitive number in GF(2m) were analyzed. A method on calculating the primitive was proposed. The simulation result shows that PSC code is a kind of efficient code for ultra wide band.

Key words: permutation sequence code, galois field, ultra wide band, timing hopping code
