摘要
周期互补序列是满足同位移周期自相关函数之和是一个冲激函数的一组序列。周期互补序列具有一些特殊的性质 ,利用这些性质 ,我们可以将它应用于扩频通信中。本文在对周期互补序列的性质和导出方法进行讨论的基础上 ,提出了基于周期互补序列的扩频通信模型和相应的解调方法。
Periodic complimentary sequences are defined as a pair of sequences with the same length characterized by the property that for the same phase-shift the sum of these periodic auto-correlations takes zero except the zero-shift. With the special characters of periodic complimentary sequences, we can use them in a spread spectrum communication system.This paper presents a spread spectrum communication system model based on periodic complimentary sequences. It is effective to eliminate the Alternate Current (AC) components included in the interference noise.
