| 摘 要： | 简要介绍UWB-OFDM系统后,分析了IEEE802.15.3a标准信道S-V模型,指出了其局限性,并基于抽样理论提出了一种较为合理的改进方案,使该模型能应用于UWB-OFDM系统,最后给出了该模型的统计特征和信道样本,计算机仿真结果表明这种新改进方法最大程度地保持了原有S-V模型的信道特性.

| Abstract: | The UWB OFDM systems are introduced briefly at first, then the IEEE802. 15.3aS V channel model is analyzed in details, and the limitation in the S V channel model is also presented. Based on the sampling theory, a more reasonable modification method for the UWB OFDM systems channel is put forward, the statistical characteristics and the pulse responses of the UWB-OFDM channel are given at last. Finally the simulation results demonstrate that the new method preserves the essence of the S V model at most. |
