Abstract

Recent works have focused on the identification of a type of linearly separable systems owning particular intrinsic symmetric/antisymmetric properties. This problem was formulated based on bilinear forms and Kronecker product decomposition. In this paper, we extend this particular symmetric filter in the context of linear system identification, aiming to estimate more general types of impulse responses. The developed solution is formulated as a Wiener filter, by deriving an iterative version exhibiting better performance features, especially in more challenging scenarios (e.g., limited amount of data and/or noisy conditions). Simulation results obtained in the context of echo cancellation indicate the appealing features of the proposed solution.
