Adaptive Nonlinearity Identification in a Hammerstein System using a Pseudo Coherence Function


A Hammerstein system consists of a memoryless nonlinear block followed by a linear time-invariant subsystem. We propose to model or to approximate the memoryless nonlinear block using a linear combination of nonlinear basis functions. We formulate a novel nonlinearity parameter estimation algorithm using a pseudo magnitude squared coherence (MSC) function… (More)
