摘要

SC-FDE(单载波频域均衡)与软分组结合ARQ技术(自动重复请求)被证明是有效的宽带无线系统与深度衰落的影响，如固有的阴影。然而，它们不适合处理强干扰效应，特别是当信道保持固定时。在本文中，我们考虑了采用SC-FDE技术的UWB(超宽带)系统在强干扰信号存在的情况下，占据了传输频带的很大一部分，我们提出了合适的软组合ARQ方案。我们的技术能够应对强干扰水平和深度衰落，即使是固定频道。

SC-FDE with soft packet combining ARQ techniques for interference-limited UWB systems

SC-FDE (Single-Carrier with Frequency-Domain Equalization) together with soft packet combining ARQ techniques (Automatic Repeat reQuest) was shown to be effective for broadband wireless systems with deep fading effects such as those inherent to shadowing. However, they are not suitable to cope with strong interference effects, especially when the channel remains fixed. In this paper, we consider UWB (Ultra Wide Band) systems employing SC-FDE techniques in the presence of strong interference signals that occupy a significant part of the transmission band and we propose suitable soft combining ARQ schemes. Our techniques are able to cope with strong interference levels as well as deep fading, even for fixed channels.
