| Abstract: | Subject,B3G-TDD OFDM system design & integration, has been checked and accepted formally in Jun 2006, as a part of the national 863 Future plan. B3G-TDD system uses wideband OFDM-MIMO technique based on TDD and is compatible with TD-SCDMA. The peak rate can reach 122 Mbit/s and its frequency spectrum efficiency gets 7.1 bit/s/Hz. Demo system supports kinds of service, such as high speed video, FTP, internet and VoIP etc. This paper introduces the B3G-TDD demo system's structure, performances, parameters, key techniques and services demo in series. |
