Abstract

We investigate the potential of adaptive equalization techniques to mitigate interchannel nonlinear interference noise (NLIN). We derive a lower bound on the mutual information of a system using adaptive equalization, showing that the channel estimation error determines the equalizer's performance. We develop an adaptive equalization scheme which uses the statistics of the NLIN to obtain improved detection based on Kalman filtering and maximum likelihood sequence estimation. This scheme outperforms commonly used equalizers and significantly increases performance.
