摘　　要：未来卫星互联网对星地之间通信速率提出了更高的要求,但当前星地单通道传输模式存在着很多限制,很难进一步提高传输速率,这种限制主要包括频率资源、器件能力、计算能力等。针对资源受限情况下,卫星互联网等新型应用对星地高通量数据传输的需求,提出一种空分复用星地高通量数据传输解决方案,给出了系统总体架构、帧结构、空间解复用及信道均衡方法等,估算了所需计算资源,在频率资源、器件能力受限情况下,可方便实现40 Gbit/s及以上的高通量传输速率。Future satellite Internet requires higher communication rate between satellite and ground,but it difficult to improve the transmission rate further subject to many limitations in current single channel transmission mode.These limitations mainly include fre⁃quency resources,device capacity,computing capacity,etc.In view of the requirement of satellite Internet and other new application for satellite⁃ground high⁃throughput data transmission under the condition of limited resources,a new space division multiplexing satellite ground high⁃throughput data transmission solution is proposed.The system’s overall structure,frame structure,spatial reuse,equalization method and computing resources are presented.Under the condition of limited frequency resource and device capability,it is easy to reach 40 Gbit/s high throughput rate data transmission or above.
