In this article, the relation between these two approaches is investigated. First, the problem of obtaining optimal convex combination coefficients is formulated as the projection of the optimal affine combination weights to the unit simplex in a weighted inner product space. Based on this formulation the closed form expressions for optimal combination weights and target MSE levels are obtained for two and three branch cases.AcousticsEngineeringElectrical and electronic engineeringComparison of convex combination and affine combination of adaptive filtersConference proceeding2689192013125004
