摘要

相关度量是衡量通信系统中码序列族性能的重要指标。跳频(FH)码在结构上与超宽带(UWB)通信系统中使用的跳时(TH)码相似。由于TH码的发展尚未完全建立，因此本文努力利用跳频码族作为TH码，因为前者大量存在并已在文献中进行了处理。本文研究了跳频码和跳频码相关特性的相似性。推导了TH码的自相关函数和互相关函数的下界，并与跳频码进行了比较。发现TH码的相关函数值高于跳频码的相关函数值。这一结论是通过对三个已建立的跳频编码序列家族的案例研究得出的。

Lower bounds of correlation measure for time hopping codes in UWB communication systems

Correlation measure is an important indicator of the performance any code sequence family used for communication system. Frequency Hopping (FH) codes are similar in construction of Time Hopping (TH) codes used in Ultra Wide Band (UWB) communication systems. Since the development of TH codes is not yet fully established, in this paper an effort has been made to utilize FH code families as TH codes as the former are widely available in large numbers and have been dealt with in literature. This paper investigates the similarity between correlation properties of FH and TH codes. Lower bounds of auto correlation and cross correlation functions of TH codes have been derived and compared those with FH codes. It is found that the values of correlation functions for TH codes are higher than those for FH codes. This conclusion has been established through a case study using three well-established FH code sequence families.
