A system for adaptively updating precoder taps comprises a first signal path, a second signal path, a delay mechanism, and logic. The first signal path is configured to receive encoded signals. The first signal path has a decoder that is configured to decode the encoded signals thereby recovering data originally transmitted from a remote transmitter. The delay mechanism is configured to receive and delay the encoded signals. The second signal path is connected in parallel with the first signal path and is configured to receive the encoded signals delayed by the delay mechanism. The second signal path has an adaptive filter configured to filter the encoded signals received by the second signal path based on a set of coefficients of the adaptive filter. The adaptive filter is configured to adaptively update the coefficients based on the data recovered by the first signal path. The logic is configured to adaptively generate new precoder taps based on the coefficients and to transmit the new precoder taps to a precoder.
