目前流行的空时处理技术的关键假设在于接收机已知MIMO信道状态信息,而MIMO信道是时变的,所以如何跟踪MIMO信道就变得十分重要。该文提出了一种基于顺序蒙特卡罗技术的窄带MIMO信道盲跟踪方法,仿真结果表明该方法能够很好地跟踪信道。
One of key assumptions of currently popular space-time processing technology is that receiver knows MIMO channel state information(CSl). Because MIMO channel is time-varying, how to track channel is veryimportant. In this paper, blind tracking of narrow-band MIMO channel based on sequential Monte Carlo is proposed. Simulation results show the good tracking of the proposed method.
