中文摘要：

卫星移动通信在国家安全、应急救援、互联网、教育及医疗、卫星电视广播以及个人移动通信等方面都有着广泛的应用，尤其在我国地理环境复杂的国情下，在国家安全及应急救灾两个方面更可直接关系到国家和民众的安危，充分发挥其不可替代的作用。宽带卫星移动通信系统可以满足未来越来越多的用户、更多业务、更多频段的业务要求，同时其也面临着系统频谱、信道资源日益紧张的局面。本课题以无线通信发展的宽带化和智能化为导向，采用可以有效利用空闲频谱的认知思想，针对卫星通信链路的时变特性、节点的移动性及OFDM子载波不连续的特点，研究Ka频段多载波OFDM卫星星地链路传输特性，并提出多载波宽带卫星通信系统星地链路宽带频谱感知方法、宽带卫星星地复杂信道的感知技术以及子载波、多用户功率联合优化机制，从而提高系统频谱利用率及系统性能，并为推进我国乃至全球实现下一代宽带星地混合系统提供理论基础和技术支持。
