摘要:
GEO 卫星通信的用户下行链路为典型的衰落信道，经卫星转发的信号如果经历大尺度衰落，则用户端接收到的 信号将产生大范围失真。该文针对 GEO 卫星通信的特点，为了提高 GEO 卫星系统的通信性能，考虑将空时协同技术引入到 GEO 卫星通信中。并仿真分析了在不同信道环境下，使用不同分集方案时 GEO 卫星通信系统性能，结果显示使用空时协同技术后， 系统的可靠性有明显提高
Abstract:
The user downlink of GEO satellite communication is typical fading channel. If the signal transponded by GEO satellites suffers a deep fade, then there will be a wide range of distortion of the signal received by the receiver. This paper introduces the space time cooperative technology into GEO satellite communication in consideration of the characteristics of GEO satellite communication. And it proposes a cooperative communication system model of two GEO satellites based on delay-tolerant space time codes. Simulation in different channel environment with using different diversity programs is conducted. The results show that whit the use of space-time technology, the transmission performance of the system has been improved significantly.
