Generalized memory polynomials have recently been proposed as an efficient means of linearization in wireless radio systems. Their unique structure provides an excellent compromise between complexity and accuracy. In the present paper, we show that the approach can successfully be transposed to optical systems. The investigated scenario is that of a CO-OFDM solution for metropolitan/access networks.
