Abstract :
Using Mobius transformations, we consider how to interpolate a set of monotone increasing data points (xk, yk) so that the interpolant is a smooth invertible function and that the interpolant and its inverse have the same simple functional form. We use our method to cancel jammer-induced distortion in a nonlinear channel
