基于順序蒙特卡羅方法的窄帶MIMO信道盲跟蹤
Blind Tracking of Narrow-Band MIMO Channel Based on the Sequential Monte Carlo Method
-
摘要: 目前流行的空時處理技術的關鍵假設在于接收機已知MIMO信道狀態(tài)信息，而MIMO信道是時變的，所以如何跟蹤MIMO信道就變得十分重要。該文提出了一種基于順序蒙特卡羅技術的窄帶MIMO信道盲跟蹤方法，仿真結果表明該方法能夠很好地跟蹤信道。Abstract: One of key assumptions of currently popular space-time processing technology is that receiver knows MIMO channel state information(CSI). 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.
