碩士 === 亞東技術學院 === 資訊與通訊工程研究所 === 97 === This research is based on S.M. Alamouti’s MIMO communication system, which has four kinds of system architecture with BPSK, QPSK, 16-QAM and 64QAM modulation technologies. For wireless channels, this research refers to John Proakis’ Channel Model and COST259 Channel Model of European co-operation in mobile radio research. For several wireless channel enviorments, the differences between MIMO architecture and traditional SISO architecture have been studied. Performance simulation includes Bit Error Rate, Spectrum Efficiency and Diversity Gain. Spectrum Efficiency and Diversity Gain are compared of different systems, modulation technologies and wireless channels based on BER of 1×10-5. Keywords: MIMO, Rayleigh Fading, Multipath Fading Channel, Space-Time Block Coding, Diversity Gain
