| Research Abstract |
The high bit-rate and highly reliable mobile packet radio technology for future multimedia communications has been theoretically and experimentally investigated. The study mainly focuses on MIMO-OFDM transmission systems where MIMO technique employing multiple antennas at both the transmitter and receiver and OFDM technique orthogonally dividing the wide bandwidth maximize the channel capacity. The study includes transmission performance improvement introducing statistical digital signal processing, reduction of degradation due to phase noise and so on, and development of wideband millimeter-wave band. The research has almost achieved the original goal.
