Abstract :
A recursive least-squares algorithm for the quadratic filter is described which has satisfactory convergence for larger filter lengths while maintaining low computational requirements. A similar least-mean-square (LMS) algorithm is also described. The respective algorithms are based on the so-called normalized recursive least-squares and normalized LMS algorithms and have considerably better performance than their unnormalized counterparts.<>
