| 摘 要： | 多用户干扰（MUI）是限制超宽带系统容量的主要因素，直接影响系统的多址接入能力．THMA技术对不同用户采用伪随机跳时序列区分，实现了多址接入．从误码性能的角度对基于THMA的2种调制方式PPM和PAM的多址接入性能进行了分析和比较，仿真结果表明，PAM调制方式的性能要好于PPM调制方式．

| Abstract: | MUI(Multi-User Interference) is the main factor that can limit the system capacity and the multiple access ability of UWB system.THMA technique uses varied pseudo-random TH sequences to distinguish the corresponding users to realize the multiple access.This paper compared the performance of multiple access by analyzing the bit error rate of PPM and PAM.The simulation results show that the performance of PAM modulation method is better than that of PPM. |
