摘要

在分析跳时(TH)序列特性的基础上，研究了多址超宽带(UWB)无线通信系统中的多址干扰问题。通过对信号模型的变换，将跳频格式描述为二进制TH序列。给出了MAI与TH相关函数的关系式。通过理论分析和计算机仿真对MAI存在下的误码率(BER)性能进行了评价。

Multiple-access interference in relation to time-hopping correlation properties in multiple-access UWB system

Based on the analysis of the properties of time-hopping (TH) sequences, this paper investigates the multiple-access interference (MAI) in multiple-access ultra-wideband (UWB) wireless communication system. By the transformation of signal model, the hopping format is described in terms of binary TH sequences. The relation between MAI and TH correlation function are formulated. The bit error rate (BER) performance in the presence of MAI is evaluated by both theoretical analysis and computer simulations.
