摘　　要：随着空间信息网络的迅速发展及人类活动的增加,移动卫星与地球站之间的通信质量要求越来越高。为了满足高速率、大容量、宽带实时通信的需求,毫米波频段应用于移动卫星通信系统引起极大关注。通过对毫米波多输入多输出(MIMO)系统中波束赋形、捕获跟踪及信道估计等关键技术的介绍,能够全面了解未来空间信息网络将要面临的挑战。With the rapid development of space information network and the increasing expansion of mankind activity, the requirements of communication quality become higher between mobile satellites and earth stations. In order to meet the demands of high data rate, large capacity and broadband real-time communication, applying millimeter wave fre-quency band to mobile satellite communication system has attracted great attention. Beamforming, tracking and channel estimation were introduced in millimeter wave MIMO system to fully understand the challenges of space information network which will face in the future.
