摘要: A method and system for blind channel estimation comprises acquiring two mixtures of at least one weakly W-disjoint orthogonal source signal, calculating point-by-point ratios a transform time-window each said mixture signals, determining parameter estimates from ratios, constructing histogram estimates, repeating the calculating, steps successive time windows selecting as parameters those associated with identified peaks on histogram.
