A Transmission Method for Sequential Power Allocation in MIMO-HARQ Systems

  • 摘要: 混合自动重传请求(HARQ)是一种保证可靠通信的差错控制方式。通过采用空分复用MIMO技术和HARQ机制,可以进行高速可靠的通信。该文提出了一种MIMO-HARQ系统中以低反馈量进行序贯功率分配的传输方法,接收机根据当前的信道信息,搜索下次HARQ重传使用的最优天线间功率分配矢量,并将其序号反馈给发射机,序贯地实现码流间的功率分配。这种方法不仅需要的反馈量少,而且对反馈延迟的要求也很低。仿真分析表明,该方法可以显著提高系统在空间相关信道下的误码性能。
