Abstract(in English) | The leaky recursive least-squares (LRLS) filter whose computational complexity is quadratic in itsfilter's length $N$ was reported by the author. The LRLS filter is derived by using the matrixinversion lemma two times in each iteration. It makes many execution time, however, since anupdate equation with the matrix inversion lemma include $N$ divisions. In this report, a fast LRLSfilter is proposed by using the matrix inversion lemma only one time and an approximation equationwith only a division. The proposed method is more effective than the conventional LRLS filters ifits filter's length $N$ is short. |
