Fast adaptation of vectoring in G.Fast

Abstract:

A device comprises a memory configured to store, for each one of a plurality of communication lines, an associated relative weight and an associated noise value indicative of a signal-to-noise ratio of transmission on the respective communication line. The device further comprises at least one processor configured to perform an optimization of a transmission precoding parameter for vectored transmission on the plurality of communication lines based on the relative weights and the noise values. The at least one processor is configured to effect the vectored transmission on the plurality of communication lines in accordance with the optimized transmission precoding parameter.
