Abstract

We propose a non Linear Wiener Hammerstein channel equalization algorithm for coherent optical OFDM system. The proposed equalization method compensates the channel non linearities. Simulations for the proposed non linear equalizer are conducted using a training sequence method to determine optimal performance through a comparative analysis. When compared to the un-equalized signals results show an improvement when using the Wiener Hammerstein equalizer. Moreover, it is shown that Wiener Hammerstein algorithm showed to be significantly beneficial for coherent optical OFDM systems. The performances of all different schemes were compared with respect to bit error rate, transmission distance, optical signal to noise ratio, power launch and error vector magnitude.
