RT Journal Article T1 Combinations of adaptive filters A1 Arenas García, Jerónimo A1 Azpicueta Ruiz, Luis Antonio A1 Silva, Magno T. M. A1 Nascimento, Vitor H. A1 Sayed, Ali H. AB Adaptive filters are at the core of many signal processing applications, ranging from acoustic noise supression to echo cancelation [1], array beamforming [2], channel equalization [3], to more recent sensor network applications in surveillance, target localization, and tracking. A trending approach in this direction is to recur to in-network distributed processing in which individual nodes implement adaptation rules and diffuse their estimation to the network [4], [5].
