| 摘 要： | 直接序列超宽带(DS-UWB)通信技术是无线通信中的一个非常有发展前途的技术.为克服无线传输中多径衰落效应,针对DS-UWB系统,提出了一种将空时编码和Rake接收结合的方案,并进行性能分析和仿真.该方案建立在码片波形,使系统不仅获得空间分集,同时获得多径分集.仿真结果表明,基于这种方案的多天线系统的性能明显优于单天线系统.

| Abstract: | DS-UWB technology is a very attractive technology for wireless communications. In this paper, an analog space time coding scheme is developed to multiantenna DS-UWB systems. It operates on chip waveforms, which make the system collect not only the spatial diversity, but also the multipath diversity. Simulation results show that the performance of multiantenna system based on STC is better than that of the single antenna system. |
