摘要
为了满足下一代移动通信的要求,提出了一种结合分集发送、调制和编码的空时编码技术。为此介绍了空时码的原理以及空时分层编码、空时栅格编码和空时分组编码的编译码方案,以及分析了空时编码在IMT-2000、OFDM等下一代移动通信系统中的应用前景等。
This paper proposed a space time coding technoiogy of combining diversity emission,modulation and coding for satis fied the demands of next generation mobile communication,therefore introduces the principle of sp ace time code and the coding plan of space time layer coding,space time fence coding and space time packet cod ing and analysis the application foreground of space time coding in next gen eration mobile commu nication system:IMT - 2000OFDM atc.
