学术讲座：Wireless MIMO Channel Modeling 时间：2007年4月10日（星期二）下午2:00--3:00 地点：校办501报告厅主讲人：英国赫瑞瓦特大学王承祥博士语言：英语 Title: Wireless MIMO Channel Modeling: Background, Comparison and Some Progress Abstract: By deploying spatially separated multiple antenna elements at both the transmitter and receiver, multiple input multiple output (MIMO) technologies can improve the link reliability and provide a significant increase of the link capacity. An appropriate characterization and modeling of MIMO propagation channels are indispensable for the development of 3G and beyond 3G wireless communication systems. This presentation starts with the review of MIMO channel models and then concentrates on the comparison of the spatial temporal correlation properties of the 3GPP Spatial Channel Model (SCM) and the Kronecker MIMO Channel Model. Despite of its simplicity and analytical tractability, the Kronecker model is restricted to characterize only the average spatial temporal behavior of MIMO channels. The SCM provides more insights of the variations of different MIMO channel realizations but the implementation complexity is relatively high. Biography: Cheng-Xiang Wang received the BSc and MEng degrees in communication and information systems from Shandong University, Shandong, P. R. China, in 1997 and 2000, respectively, and the PhD degree in wireless communications from Aalborg University, Aalborg, Denmark, in 2004. From 2000 to 2001, he was a Research Assistant with the Department of Communication Networks, Technical University of Hamburg-Harburg, Hamburg, Germany. From 2001 to 2005, he was a Research Fellow of mobile communications with Agder University College, Grimstad, Norway. From January to April 2004, he was a Visiting Researcher at Baseband Algorithms & Standardization Lab of Siemens AG-Mobile Phones, Munich, Germany. Since 2005, he has been a Lecturer in Mobile Communications and Networks, Heriot-Watt University, Edinburgh, UK. Since June 2006, he has been an honorary fellowship of the University of Edinburgh and an adjunct professor of Guilin University of Electronic Technology, P. R. China. His current research interests include mobile propagation channel modeling, error models, smart antennas and (virtual) MIMO systems, OFDM, UWB, cognitive radio, space-time coding, cross-layer design of wireless networks, mobile ad hoc and wireless sensor networks, and 3GPP long term evolution. He has published about 70 papers in journals and conference proceedings. He received the ?999 Excellent Paper Award?for two of his papers from the sixth National Youth Communication Conference of China, Beijing, P. R. China. He serves as an Editorial Board member for Wireless Communications and Mobile Computing (WCMC) Journal and a TPC member for 14 major international conferences including IEEE VTC 2005-Fall, ICIC 2006, Globecom 2006, WCNC 2007, ICC 2007, and ICIC 2007. He also serves as Session Chair for ICCCAS 2006. He is a member of the IEEE and the IET. 爱丁堡赫瑞·瓦特大学位于苏格兰首府爱丁堡市郊。是一所具有一百多年历史的英国国立大学，其建校史可追溯到1821年，1966年获皇家特许状成为大学。赫瑞·瓦特大学的校名是为纪念在技术方面做出巨大贡献的苏格兰两位开发者，即英国皇家的金融架乔治赫瑞与蒸汽动力研究的先驱者杰姆斯瓦特。赫瑞瓦特大学是一所充满活力的现代化高等学府，在1996年12月被皇家工程协会评为苏格兰一流的工程技术研究单位。爱丁堡赫瑞瓦特大学一向得到工商业界的大力支持，光电子学／激光、土木工程与建筑工程、潜海／石油科学以及信息技术等专业是该大学的强项。其科研收入中学校总收入的45%，在全英一百多所商校中名列前茅。在2006年评比的结果是，赫瑞·瓦特大学的科研总收入在全英高校中名列第九名，其人均科研收入在全英排名第二，超过的了牛津、剑桥、以及帝国理工学院。2006年Heriot-Watt 大学毕业生就业率苏格兰地区名列第一，英联邦国名列第五。赫瑞瓦特大学共有全日制学生9,000名，其中10％以上是来自欧洲以外的其他国家的留学生。这些来自70多个不同国家的留学生在校园内相处得十分融洽。学术讲座之后，王博士将留出半小时的时间与大家进行交流，介绍其学校并回答大家各方面的问题。校学术委员会国际处 2007年4月6日
