Abstract

This paper proposes an improved learning scheme for MIMO-FEL (Muliti-input multi-output feedback error learning) of prefilter-integration-type. Compared with an existing scheme, which is based on the gradient method and easily implemented, the proposed scheme does not require positive realness of the closed loop system. The paper shows the parameters converge to true values under a PE condition, and verifies its effectiveness in terms of simulation.
