Abstract

A new RLS adaptive Volterra filter is presented. The nonlinear filtering problem is transformed into an equivalent multichannel. but linear, filtering problem. The multichannel input signal is completely orthogonalised using sequential processing multichannel lattice stages. Thus, the channel is identified directly and parameters for the channel nonlinearity are simultaneously quantified.
