A low-cost and fast convergence Gauss-Seidel pseudo affine projection algorithm for multichannel active noise control

It is well known that fast affine projection algorithms can produce a good trade-off between convergence speed and computational complexity. In this paper, we propose a new pseudo fast affine projection algorithm based on the Gauss-Seidel scheme for multichannel active noise control (ANC) systems. It is shown that the proposed algorithm has a lower complexity than previously published fast affine projection algorithms, with similar convergence properties and better numerical stability.
