摘要
建立天地一体化网络是实现全球范围内我国的政治、军事和经济利益保障的重要手段。首先对当前国内外相关的典型系统进行了分析,然后对天地一体化网络涉及的与地面系统融合的空中接口技术的发展进行了简要介绍,针对OFDM和FBMC多载波传输技术在空间通信中应用的PAPR问题进行了分析,最后提出一种利用Massive MIMO技术结合星群改善卫星功率受限条件下系统容量的方案。
The space and terrestrial integrated network is an important information infrastructure to support China＇s political, military and economic interests on a global scale. Firstly, the current situation and development trend of GIG, TCA, SCaN and other related system are analyzed. Then this paper introduces air interface technology which supports the development of such network.The PAPR problem of OFDM and FBMC in space communication is described in detail.Based on massive MIMO and constellation,a novel method based on is proposed to improve the system capacity under constrained power condition.
