摘要

本文介绍了具有额外分集的超宽带多频带正交频分复用(UWB MB-OFDM)系统的性能。为了在当前采用时域扩频(TDS)和频域扩频(FDS)的MB-OFDM系统中充分获得分集增益，设计了两个连续的OFDM符号相互循环移位。仿真结果表明，采用附加频率分集的MB-OFDM优于传统的MB-OFDM。

Performance of MB-OFDM UWB Systems with Extra Diversity

This paper presents the performance of ultra-wideband multi-band orthogonal frequency division multiplexing (UWB MB-OFDM) systems with extra diversity. To fully obtain diversity gain in the current MB-OFDM system when time-domain spreading (TDS) and frequency-domain spreading (FDS) are adopted, two consecutive OFDM symbols are designed to be cyclic shifted each other. Simulation results show that the MB-OFDM using additional frequency diversity outperforms conventional MB-OFDM.
