摘　　要：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 algorithm is one of recursive least squares algorithms.It has much faster equalizer convergence than the gradient algorithm.Its complexity is much less than convertional Kalman algorithm.It particularly adapts to track rapid variation of a communication channel as an ionosphere. In this paper fast Kalman algorithm applying to a decision feedback equalizer has been exhaustively researched.
