| 摘 要： | 提高频率利用率一直是移动通信系统中的研究热点,而近年来提出的空时码又是其关键技术之一.从当前的研究情况来看,空时码技术主要分为以下两大类:一是分层空时码(LST);二是基于发射分集的空时分组码和空时格码.由于空时码具有良好的频带利用率及性能,3GPP已将空时分组码作为一可选方案列在所提规范之中.相信在不远的将来,空时码必将广泛应用于未来的移动通信系统.

| Abstract: | To improve frequency efficiency is always a hotspot in mobile communication systems.One of the key technologies proposed recently is space-time code.According to the up-to-date researches,space-time code is divided into two main categories.One is the layered space-time code;the other includes space-time block code and space-time trellis code which are based on transmit diversity.Because of good spectrum efficiency and performance,space-time code has been proposed as an optional scheme in 3GPP specification.We can imagine that space-time code will be widely applied in mobile telecommunication systems in the near future. |
