Sparse complex FxLMS for active noise cancellation over spatial regions

Zhang, Jihui; Abhayapala, Thushara; Samarasinghe, Prasanga; Zhang, Wen; Jiang, Shouda


In this paper, we investigate active noise control over large 2D spatial regions when the noise source is sparsely distributed. The l1 relaxation technique originated from compressive sensing is adopted and based on that we develop the algorithm for two cases: multipoint noise cancellation and wave domain noise cancellation. This results in two new variants (i) zero-attracting multi-point complex FxLMS and (ii) zero-attracting wave domain complex FxLMS. Both approaches use a feedback control...[Show more]
