| Popis: | 95 LMDS (Local Multipoint Distribution Service) is the point to multi-point fixed wireless broadband access system and adopts cellular system to provide high-speed service such as: broadband access, video, message, data, etc. LMDS reduces the cost of traditional connection which uses coaxial cable or other wired method and is suitable for “Last-Mile “wireless access technique. Today multiple antennas transmission technique provides better system performance and higher data rate effectively. Multiple antennas transmission technique includes Beamforming, Space Time Code, and Spatial Multiplexing. Beamforming provides resistance to interference obviously, Space Time Code improves the error performance against multi-path fading channel, and Spatial Multiplexing provides higher data rate. In this thesis, we will make use of some multiple antennas transmission technique to analysis the bit error rate performance and spectrum efficiency of LMDS cellular system by computer simulation. |
