Blind Processing Algorithm Based on Probability Density Estimation



Most algorithms for resolving the problems of blind source separation (BSS) and blind deconvolution are mainly focused on blind separation for mixed signals using higher order statistics of random signals, including third-order (for sources with dissymmetrical distribution) and fourth-order cumulant (for sources with symmetrical distribution). Usually, this kind of method directly employs an algebraic structure of a mixed signal cumulant matrix. The common method makes eigenvalues decomposition to the cumulant matrix that is estimated by the mixed signal samples. It can also perform joint diagonalization for the cumulant matrix through complex matrix transformation to estimate the mixing matrix in order to solve the BSS problem.
