Abstract(in English) | In recent years, an LRLS algorithm which is more accurate and stable in a noisy environment than the RLS algorithm has been proposed. However, since the LRLS algorithm needs to compute a matrix inverse in each iteration, the computational complexity in the LRLS algorithm is on the order of M^3. In this report, since a matrix inverse is approximately computed by using discrete cosine transform, the LRLS algorithm whose computational complexity is reduced from the order of M^3 to the order of M^2 is considered. |
