Abstract
A computer-implemented method of training a self-coherent detector module to recover distorted optical transmission signals, and processing devices adapted to perform the method are disclosed. The detector module comprises an optical filter unit, a detection unit for detecting an amplitude component of an optical input, and digital signal processing circuitry configured to retrieve a phase component of the optical input from the amplitude component. The method comprises iteratively computing updates of adjustable filter coefficients of the filter unit, based on a received first dataset, and replacing training signals of the first dataset, taking the updated filter coefficients into account. An initial set of filter coefficients is pre-trained on a received second dataset. Training signals of the first and second dataset comprise distorted optical transmission signals that are subjected to filtering by the filter unit.
