IDENTIFICATION OF NONLINEAR MAGNETIC CHANNELS WITH LATTICE ORTHOGONALIZATION

A new RLS adaptive Volterra filter is presented. The nonlinear filteri ng problem is transformed into an equivalent multichannel. but linear, filtering problem. The multichannel input signal is completely orthog onalised using sequential processing multichannel lattice stages. Thus , the channel is identified directly and parameters for the channel no nlinearity are simultaneously quantified.
