项目摘要

Providing high speed connection to moving cars driving through remote area with limited infrastructure represents a promising application area for future satellite communication industry. One of the key technical challenges is to develop low-profile cost-effective high performance antennas for SOTM (Satcom-On-The-Move) terminals. Existing solutions typically entails high implementation complexity, which limits their application to standard commercial cars. In this research project, we propose to develop effective and low-complexity solutions for SOTM antennas. The objective is to achieve comparable link performance with conventional parabolic reflection antennas with much lower profile and no mechanical tracking parts. We plan to explore the recent advanced in the area of multiple antenna transmission and receiver technologies, massive MIMO technologies more specifically, to address this challenging design problem. The proposed approach will adaptively utilize a large number of antenna elements based on their instantaneous channel state information, which has the potential to lead to much improved performance than previously proposed phased array antennas. The technology developed from the proposed research program will be directly applied to Canadian private sector and enhance the competition advantage of Canadian company in the field of mobile satellite antennas.

为行驶在基础设施有限的偏远地区的移动汽车提供高速连接代表了未来卫星通信行业的一个有前景的应用领域。关键技术挑战之一是为 SOTM（移动卫星通信）终端开发薄型、经济高效的高性能天线。现有的解决方案通常需要很高的实施复杂性，这限制了它们在标准商用车上的应用。在这个研究项目中，我们建议为 SOTM 天线开发有效且低复杂性的解决方案。目标是实现与传统抛物面反射天线相当的链路性能，且外形要小得多且没有机械跟踪部件。我们计划探索多天线传输和接收技术领域的最新进展，更具体地说是大规模 MIMO 技术，以解决这一具有挑战性的设计问题。所提出的方法将根据瞬时信道状态信息自适应地利用大量天线单元，这有可能比之前提出的相控阵天线显着提高性能。拟议研究计划开发的技术将直接应用于加拿大私营部门，并增强加拿大公司在移动卫星天线领域的竞争优势。
