摘　　要：多用户、高速率的无线网络已经成为未来无线通信网络的发展趋势,新兴的MB-OFDM超宽带技术因其一系列显著的优点越来越受到人们的关注。现分析了基于FFT和IEEE802.15.3a标准的两种MB-OFDM超宽带系统模型及其多址接入方式。从接收机复杂度、系统性能、误码率等方面比较了这两种多址方式优缺点。The wireless network with multi-user and high speed becomes the developmental tendency of the future wireless communication network. The rising technology of MB-OFDM ultra-wide band is coming to front day by day, because of its remarkable advantages. This article analyzes MB-OFDM ultra-wide band system models based on FFT and IEEE802.15.3standard, and their multiple-access schemes. It compares the complexity of the receiver and the system performance of these two multiple-access schemes. The simulations confirm the advantage of the multiple-access scheme based on FH-OFDM UWB system.
