卡尔曼滤波器进行信道估计的一篇文章，适用于OFDM-MIMO系统。-Kalman filter for channel estimation in an article for OFDM-MIMO systems.

Channel estimation techniques for OFDM systems based on a pilot arrangement are investigated. Channel estimation based on a comb type pilot arrangement is studied through different algorithms for both estimating the channel at pilot frequencies and i
