摘　　要：针对卫星移动信道,提出了一种基于链路层(Link Layer)的混合自动请求重传(HARQ)技术联合物理层(Physical Layer)自适应编码调制(AMC)技术的L/P跨层设计;在Nakagami-m信道模型中验证其性能,并与非跨层设计结果作了对比。理论分析及仿真比较结果表明,这种跨层设计可以综合有效地优化卫星移动通信性能。This paper proposes a L/P cross-layer design based on hybrid automatic repeat request （HARQ） of link layer com bining with adaptive modulation and coding （AMC） of physical layer to be applied in satellite mobile communications. It is valued onehannel model and compared with that of non-cross-layer design. By the theory analysis and results of simulation, it can be found that the design can improve the performance of satellite mobile communications synthetically and effectively.
