摘要
In this letter, an adaptive recursive nonlinear filter based on the Volterra series and an infinite impulse response (IIR) structure is considered, For certain types of nonlinear systems where high-order nonlinearities are recursively general-ed, we show that the adaptive recursive second-order polynomial filter has improved performance over the well-known (nonrecursive) adaptive second-order Volterra filter and a third-order Volterra filter, This filter represents an alternative to using a traditional Volterra filter whose order has been increased to match that of the system being modeled.
