It may be seen as a generalization on EM using the ideas of Cascade EM algorithm and Space Alternating Generalized EM algorithm. Also, for passive data acquisition, robust and efficient alternatives for the estimation of the source signals are investigated.EnglishData acquisitionOptimizationParameter estimationSensorsSignal processingTrees (mathematics)Cascade algorithmDirection of arrivalsMeasured signalsSource signalsSpace alternating generalized algorithmTree structured expectation maximization algorithmWide band maximum Angle of arrival estimationAlgorithmsConference Paper10.1109/SSAP.1996.534937
