A new second-order method for blind signal separation from dynamic mixtures
journal contribution
posted on 2004-07-01, 00:00 authored by Yong XiangYong Xiang, Saeid Nahavandi, Hieu TrinhHieu Trinh, H ZhengThis paper presents a new approach to separate colored stationary signals mixed by convolutive channels. A cost function is proposed by employing linear constraint to the demixing vectors. The linear constraint is shown to be sufficient for avoiding trivial solution. The minimization of the cost function is performed using the Lagrangian method. Simulation results demonstrate the performance of the algorithm.
