Advanced Technologies for Energy-Efficient Cooperative Wireless Communication Systems

近年来，无线行业经历了巨大的增长，预计这将在未来几年继续下去。因此，无线通信系统的总能耗不再可以忽略。 此外，诸如智能电话和iPad的移动的设备支持诸如Youtube和无线网络上的视频会议的应用，这些应用需要每秒兆比特量级的高传输速率。 迄今为止，无线系统主要在带宽效率和通信可靠性方面进行了优化。 然而，对提高现代通信系统的能量效率的需求日益增加。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的设备的电池寿命。虽然制造商和运营商的目标是降低整体功耗，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提出了重大挑战。 建议的研究的目的是设计创新的技术，可以提高能源效率的下一代无线通信系统，依赖于所谓的“合作”机制之间的通信用户/节点在网络中。 特别是，使用一个整体的设计方法，我们计划开发新的无线发射机/接收机对和无线电资源分配方案的合作通信系统，可以节省传输信号的能量显着。 这项研究计划的成果预计将推动知识和技术，以实现节能的无线网络通信行业。这不仅将延长移动的设备的电池寿命，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.
