Sequential Blind Extraction Adopting Second-Order Statistics
Xi-Lin Li, Xian‐Da Zhang · IEEE Signal Processing Letters · 2006
This letter proposes a novel second-order statistics-based sequential blind extraction algorithm via approximate joint diagonalization of autocorrelation matrices. The proposed algorithm is computationally simple and efficient and can extract specific sources if some a priori knowledge is available. An experiment on real-world ECG data validates the good performance of the proposed algorithm
