摘要
文章介绍了分组空时码和分层空时码,给出了它们在3G和后3G中的解决方案;分析了限制网格空时码应用的几个因素,提出了网格空时码应用的具体方案;最后对分组空时码、分层空时码、网格空时码进行了比较。
The s pace-time block codes and layered s pace-time codes are briefly des cribed.The s olution s chemes of their appli-cations in3G and beyond3G wireles s communication s ys tems are pres ented.Bas ed on the analys is of problems exis ted in the application of s pace-time trellis codes,a practical s olutions s cheme is propos ed.Finally the future applications of s pace-time block codes(STBC),layered s pace-time codes(LSTC)and s pace-time trellis codes(STTC)are outlined.
