Abstract :
This paper deals with the affine projection algorithm (APA) and the block orthogonal projection algorithm (BOPA) with a step size matrix. This paper proposes a design method providing an optimal step matrix that is robust in some sense. The convergence property of APA is described as linear matrix inequalities (LMIs) and the design problem is reduced to a semidefinite program (SDP) which is a convex optimization problem and can be solved in a polynomial time. The numerical example shows the effectiveness of the proposed method.
