Resource allocation scheme under rain fading in multi-beam mobile satellite systems

  • 摘要: 针对雨衰对高频段的卫星通信造成的不利影响,采用自适应前向纠错编码(FEC,Forward Error Correction)使传输的信息量减少,提出了一种雨衰下的自适应信道分配的策略.该方法是采用调整冗余信道来保障信息信道的传输量以满足系统对误码率的要求,达到可靠和有效地利用有限的卫星信道资源的目的.通过仿真分析了该策略针对不同的频段和降雨情况下对呼叫产生的影响,分析中考虑了话音业务享有比数据业务更高的优先权.仿真结果表明利用冗余信道传输用于纠错的冗余信息可以保证在不产生通信中断的前提下,可以满足系统对信道误码率的要求.
