Transceiver circuit

A transceiver circuit for transmitting and receiving signals within a network, wherein the transceiver circuit comprises:

• a transceiver clock input terminal configured to receive a transceiver clock signal that defines a network frequency;
• a clock provision circuit configured to provide, as a coefficient clock signal defining a coefficient frequency, a selected one of:
• i) a first clock signal defining a first frequency or ii) a second clock signal defining a second frequency that is lower than the first frequency, based on a received rate-selection-signal;
• a coefficient adaption unit for providing a coefficient signal that represents one or more coefficient values, wherein
• the coefficient adaption unit is configured to update the one or more coefficient values at the coefficient frequency;
• and
• an adaptive filtering circuit, comprising:
• at least one coefficient input terminal connected to the coefficient adaption unit for receiving the coefficient signals,
• a filter input terminal for sequentially receiving a stream of interference-symbols at the network frequency, and
• a filter output terminal for providing an interference-error signal, wherein the interference-error signal is to be removed from a network signal,
• wherein the adaptive filtering circuit is configured to:
• apply a plurality of scaling factors to the coefficient signal to create a plurality of scaled coefficient signals, and
• selecting, based on the received interference-symbols, one of the scaled coefficient signals to use to provide the interference-error signal.
