In this paper low-complexity equivalent realizations for multirate Volterra systems are presented. All analysed filter configurations contain in addition to the nonlinear filter both an upsampler and a downsampler. Using Volterra filters a wide class of nonlinear systems can be approximated with arbitrary precision. Also special cases, like cascades of(More)
The work addresses the problem of approximating the sampled input-output (i/o) behavior of continuous-time nonlin-ear systems using discrete-time Volterra models. For an exactly band-limited nonlinear system for which a Volterra representation exists, the discrete-time Volterra model exactly corresponds to the sampled continuous-time Volterra kernels.(More)
