Weighted least-squares blind deconvolution of non-minimum phase systems

A new algorithm based on a weighted least-squares technique is proposed tha t allows online deconvolution of non-minimum phase systems with neither kno wledge of the system's impulse response nor source statistics except for so urce signal moments up to the fourth order. Using computer simulations and computational complexity evaluation, the authors illustrate and compare the performances and the features of the proposed method with those of other t echniques found in the literature.
