Abstract

The G.fast is the most recently DSL standard released by the ITU. The G.fast deployment environment is very noisy, in which several external interferences may impair the transmission. One of the most problematic interference source is the alien xtalk. Despite the difficult to mitigate this type of interference, there are some mitigation methods that reduce the impact of the alien xtalk over DSL systems. However, these methods present a setback that is to unbalance the transmission rates achieved by the coordinated lines. In this paper we propose an empirical method to achieve rate balancing simultaneously with alien xtalk mitigation. Additionally, we present a set of simulation results performed with cable
