Advanced Technologies for Energy-Efficient Cooperative Wireless Communication Systems

无线行业近年来经历了巨大的增长，预计这种增长将在未来几年继续下去。因此，无线通信系统的总能耗不能再被忽略。此外，智能手机和iPad等移动设备支持YouTube和无线网络上的视频会议等应用程序，这些应用程序需要每秒兆比特的高传输速率。到目前为止，无线系统在带宽效率和通信可靠性方面得到了最大程度的优化。然而，人们越来越需要提高现代通信系统的能效。一个主要原因是减少通信网络的净碳足迹。另一个原因是延长移动设备的电池寿命。虽然制造商和运营商的目标是降低总体功耗，但所支持的服务要求更高、更快的数据速率、更低的延迟和更大的服务覆盖范围。这些相互竞争的需求对设计和部署现代无线通信系统构成了巨大的挑战。提出的研究目的是设计创新技术，以提高下一代无线通信系统的能量效率，这些系统依赖于网络中通信用户/节点之间的所谓合作机制。特别是，我们计划采用整体设计的方法，为协作通信系统开发新的无线收发机对和无线资源分配方案，以显著节省传输信号能量。这一研究计划的成果有望为通信行业提供先进的知识和技术，以实现节能的无线网络。这不仅将延长移动设备的电池寿命，还将通过减少能源消耗和电磁辐射来拯救加拿大的环境。

The wireless industry has experienced a tremendous growth in recent years and this is expected to continue in the years to come. As such the overall energy consumption of wireless communication systems cannot be neglected any longer. Additionally, mobile devices such as smart phones and iPads support applications like Youtube and video conferencing over wireless networks that require high transmission rate in the order of Megabits per second. To date, wireless systems have been mostly optimized in terms of bandwidth efficiency and reliability of communication. However, there is an increasing need to improve energy efficiency of modern communication systems. One main reason is to reduce the net carbon footprint of communication networks. The other reason is to prolong the battery life for mobile devices. Whilst the manufacturers' and operators' objective is to reduce overall power consumption, the supported services are demanding higher and faster data rates, lower latency and increased service coverage. These competing needs pose a significant challenge in designing and deploying modern wireless communication systems. The objective of the proposed research is to design innovative technologies that can improve energy efficiency for future generation wireless communication systems that rely on so-called "cooperation" mechanism among the communicating users/nodes in the network. In particular, using a holistic design approach, we plan to develop novel wireless transmitter/receiver pair and radio resource allocation schemes for cooperative communication systems that can save transmission signal energy significantly. The outcome of this research program is expected to advance knowledge and deliver technologies to communication industries in order to implement energy-efficient wireless networks. This will not only prolong the battery life of mobile devices but will also save the Canadian environment by reducing energy consumption as well as electromagnetic radiation.
