Space Time Coding Technology in Next Generation Mobile Communication

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.
