An extended iterated-function-system (IFS) interpolation method is pre
sented for modelling for a given discrete signal. To reduce the comput
ing complexity a suboptimal search algorithm with a robust technique f
or estimating the IFS affine-map parameters is introduced. Simulation
results show that the IFS approach achieves a higher signal-to-noise r
atio than does an existing approach based on autoregressive modelling.
