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