| 摘 要： | 基于跨层设计的思想,将物理层的信道状态和MAC层的接入策略联合考虑,提出了CFDAMA-CCSI(combined channel state information)协议。根据信道状态的动态变化,终端和卫星调度器调整接入策略。仿真结果表明,在雨衰环境中,该策略有效提高了信道利用率,改进了时延性能。

| Abstract: | Based on the idea of cross-layer design,in consideration of both channel state in physical layer and access scheme in MAC layer,a novel MAC protocal,called CFDAMA-CCSI protocal using channal state information was proposed.According to the channel state,the terminals and satellite dynamically adjust the access scheme.Simulations demonstrate that the proposed protocol can increase channel utilization effeciency and improve delay performance. |
