摘　　要：空时编码技术和超宽带技术是当前无线通信领域的热点技术。为了提高短距高速率无线通信的性能,讨论了空时编码技术在超宽带通信系统中的应用方案,由于超宽带脉冲信号具有极窄的时域支撑区,而且信道为密集多径信道,因此超宽带通信系统中的空时编码技术具有完全不同的特性,提出了几种超宽带空时编码方案,并对其性能优缺点进行了分析比较。Space- time coding and Ultra- Wideband（UWB） are the fast developed technology in the area of short range wireless communication. In order to boost the performance of short range wireless communication, the scheme of applying space - time coding in UWB communication system is discussed in this paper. With ultra short pulse in time domain and dense multi - path channel,the UWB space - time coding is quite different from the conventional space - time coding. Based on the analysis of several UWB space - time coding schemes, the performance of that are compared.
