Abstract: Embodiments relate to a method and an apparatus for predicting the bitrate of a repaired communication channel. The method may comprise: generating a dataset specifying, for a plurality of communication channels: a channel frequency response of a communication channel affected by an impairment, and a channel frequency response of the communication channel non-affected by said impairment, training, based on the dataset, a machine learning model configured for predicting, based on the channel frequency response of an impaired communication channel, the channel frequency response of the repaired communication channel.
