Mitigation of Alien Crosstalk for Downstream DSL Impaired by Multiple Interferers

Gomes, Diego; Medeiros, Eduardo; Klautau, Aldebaro; Pelaes, Evaldo

Alien crosstalk is one of the major impairments for copper-based transmissions. This letter outlines a method for mitigating alien crosstalk for digital subscriber line downstream transmissions impaired by multiple interference sources. The method requires a reference channel, and includes a post-processing stage in which induced correlation is applied to prepare the interference at the target channel to be reasonably removed by a prediction-based mitigation step. The results show that the proposed method outperforms published alien crosstalk mitigation methods as the number of interference sources increase in G.fast scenarios.
