MIMO_OFDM时变信道修正KALMAN跟踪-Time-varying channels MIMO_OFDM amendment Kalman tracking

快速卡尔曼算法是递推最小二乘算法中的一种, 它的收敛速度比梯度算法快得多, 其计算量又比常规卡尔曼算法少得多, 特别适合于跟踪像电离层这样的快变化时变信道。 本文对 用于自适应均衡的快速卡尔曼算法进行了详细研究。-Fast Kalman algo r ithm is one of recursive least squares algo r ithm s . It has much faster equalizer convergence than the gradient algo
