信息工程学院高质量发展之学术报告第十三讲

为了进一步加强学院学术氛围，跟踪学科前沿，与国内外优秀同行建立良好合作关系，提高学院学术影响力，同时扩大师生视野，提高师生学术创新能力，提高学院发展质量，我院将开展系列学术报告，本次报告为系列报告第十三讲。

报告主题：Dual-Hop AF Relaying Communication Systems over Mixed Generalized Fading Channels

报告大纲：研究源到中继和中继到目的信道受不同衰落条件影响的双跳放大转发(AF)中继通信系统的端到端性能。我们考虑了一跳信道受n-u衰落而另一跳信道受K-u衰落的混合广义衰落信道的情况。这种混合衰落传播信道能够准确地模拟各种实际的双跳传输。这种环境的例子是在微/宏蜂窝系统和/或混合卫星/地面无线通信系统中遇到的，其中通常只有一跳的信道具有视距组件。对于csi辅助中继和定增益中继，以及整值衰落参数，导出了几种调制方案的中断概率(OP)和平均误码率(ABEP)的快速收敛无穷级数的精确解析表达式。此外，对于csi辅助中继和任意值衰落参数，获得了OP和ABEP性能的封闭下界(高信噪比时较紧)。该分析还通过获得先前发表的等效性能表达式作为我们的广义衰落模型的特殊情况得到证实，即适用于Nakagami-m和Rice衰落信道的等效性能表达式。

From 1982 to 1986, he was with Raytheon Canada Ltd., working in the areas of air navigational and satellite communications. In 1989, he joined the Department of Electrical and Computer Engineering (ECE), University of British Columbia (UBC), Vancouver, Canada, as an Assistant Professor until 2003. He was the Director (2000 - 2004) and the Director of Research of the Institute for Space Applications and Remote Sensing (ISARS), National Observatory of Athens (NOA). Since 2014, he is Professor at the National and Kapodistrian University of Athens, Greece. He also held visiting faculty long term honorary academic appointments as Guest Professor at South West Jiao Tong University (SWJTU), Chengdu, China, and Guest (Global) Professor at Keio University, Tokyo, Japan. His research area is within the wireless terrestrial and satellite communication systems and network as well as in remote sensing, LiDAR systems. He has published 140 journal papers, 1 book, 5 book chapters, and more than 140 conference papers. He has been or currently serves on the editorial board of several archival journals, including IET Communications, IEEE Transactions on Communications, Remote Sensing Journal, and as Specialty Chief Editor for the Arial and Space Network Journal of Frontiers. He has served as a Greek Representative to high-level committees in the European Commission and the European Space Agency. He has been awarded an Advanced Systems Institute (ASI) Fellowship as well as a Killam Research Fellowship. He is also the co-recipient of two best conference paper awards and has received by the IEEE Communication Society the Satellite and Space Communication Technical Committee “2017 Distinguished Service Award” for outstanding contributions in the field of Satellite and Space Communications.
