学术讲座通知报告题目：MIMO Mobile-to-Mobile Propagation Channel Modelling: Recent Advances and Future Challenges 报告人：Dr. Cheng-Xiang Wang（Heriot-Watt University, Edinburgh, UK. http://www.ece.eps.hw.ac.uk/~cxwang/ ）时间：7月7日（星期一）下午3：00 地点：教三楼111 摘要：Mobile-to-mobile (M2M) channel modelling has received much attention recently due to the increasing applications of intelligent transportation systems, wireless mobile ad hoc networks, and relay-based cellular networks, where both the transmitter and receiver are normally in motion and equipped with lowly elevated antennas. Multiple-input multiple-output (MIMO) technology is very promising for M2M communications since multiple antenna elements can be easily placed on large vehicle surfaces. In this talk, I will first start with an overview of recent advances in this area. Then, a generic and adaptive geometrical-based stochastic reference model is proposed for MIMO M2M Ricean fading channels. The proposed model employs a combined two-ring model and elliptical-ring model, where the received signal is constructed as a sum of the line-of-sight (LoS), single-bounced, and double-bounced rays with different energies. This makes the model sufficiently generic and therefore includes many existing channel models as special cases. Also, the model can easily be adapted to a variety of M2M propagation environments, e.g., outdoor macro- and micro-cells taking into account different traffic volumes, by adjusting model parameters. Some important statistical properties of the proposed model are studied, e.g., the space-time-frequency (STF) correlation function (CF), space-Doppler-frequency (SDF) power spectrum, and Doppler power spectrum. The talk will be concluded by addressing future challenges in this area. 此报告为前沿讲座，欢迎全校师生踊跃参加。校学术委员会电信工程学院 2008年7月7日 Biography Cheng-Xiang Wang received the BSc and MEng degrees in Communication and Information Systems from Shandong University, Shandong, P.
