这封信提出了一种有限脉冲响应（FIR）信道估计滤波器，具有鲁棒性的信道失配，由于FIR结构。信道冲激响应用复状态空间模型描述，然后从最近时间间隔上的接收数据估计。数值结果表明，当信道模型参数不正确时，FIR信道估计滤波器比传统的卡尔曼IIR滤波器具有更好的鲁棒性。
This letter proposes a finite impulse response (FIR) channel estimation filter that has robustness against the channel mismatch due to the FIR structure. The channel impulse response is described with a complex state space model and then estimated from received data on the recent time interval. Numerical results show that the FIR channel estimation filter can provide more robust performance than conventional Kalman IIR filters when channel model parameters are not correct.
