Abstract :
The need to recover the original input from the output of a nonlinear system is a common problem in many applications. We propose a new method for Volterra system equalization based on finding the roots of a polynomial of the input. The method is capable of equalizing severe nonlinearities under the assumption that the input comes from a finite symbol set. Numerical simulations demonstrate its performance under a wide range of conditions.
