A recursive least square algorithm for active noise control based on the Gauss-Seidel method

In this paper, a new recursive least-squares algorithm (RLS) for multichannel active noise control using the Gauss-Seidel method is proposed. It is shown that the proposed algorithm has a much lower complexity than the previously published modified filtered-x RLS algorithm, with similar convergence property and good numerical stability. Its logarithmic number system implementation is also presented.
