  • Abstract
    A technique for realising nonlinear functions of order ≥5 using cascaded third-order nonlinear functions is described. The technique can be used to efficiently generate higher-order nonlinearities for predistortion linearisation applications. The use of two cascaded third-order functions is experimentally demonstrated to be comparable to a fifth-order implementation in performance.
