THE DIVIDED-STEP SQUARE ROOT KALMAN FILTERING FOR HF CHANNELS
短波信道的分步平方根卡尔曼滤波

This paper develops a divided-step square root Kalman filtering theory based on the classical square root Kalman filtering and the gradient algorithm. Using these two algorithms, various simplified algorithms can be formed. Their computation time is much reduced, but their performances are not degraded remarkably. So, this filtering theory is mors adaptable for high-speed data transmission systems.
