英文摘要： Because of the advantages of high-rate transmission, flexible use of frequency band and high efficiency, multiband impulse ultra wide-band (MultiBand-IR-UWB) has been the focus of the academics' attention. Then, the feature of the combination between high-rate transmission of MultiBand-IR-UWB and diversity multiplexing of multiple antenna can effectively improve the frequency efficiency and flexibility of UWB communication system. And the potential of improving the anti-noise performance needs to be further excavated.So, many basal researches in the technology, including modeling for multiple antenna transmission scheme and performance, are very worthwhile to study currently. Starting from the working principle of Multiband-IR-UWB, the transmission theory, implementation methods and theory mechanism of exploring the performance advantage are discussed. Moreover, the theory basis of transmission methods and performance and accuracy of mathematical model and channel model are mainly studied. The key technologies consist of the design of assignment methods by avoiding frequency-band interference, the research of signal separation methods based on linear filter and joint channel estimation algorithm between adjacent channel on the condition of multiple antenna. These key technologies are also discussed as the conte
