| Abstract: | A least square algorithm immunizing from decaying DC component is proposed in this paper, which is based on the numeral process of filtering results of least square. The influence of running frequency on the algorithm and how to eliminate the influence are discussed. Except lesser computation amount, the new algorithm has no relation to the decaying constant and exists a relatively low time delay. Theoretical analysis and simulation show that the principle of the new algorithm is correct, and the computation result is accurate. |
