Abstract
A filter circuit, method of configuring the filter circuit, and a bit pump and transceiver employing the circuit and method. In one embodiment, the filter circuit includes a noise prediction equalizer that generates a noise prediction equalizer coefficient during activation of the bit pump to reduce an intersymbol interference associated with a receive signal propagating along a receive path of the bit pump. The filter circuit also includes a decision feedback equalizer that generates a decision feedback equalizer coefficient during the activation of the bit pump to reduce the intersymbol interference associated with the receive signal. The noise prediction equalizer is concatenated with the decision feedback equalizer during showtime of the bit pump to form a precoder associated with a transmit path of the bit pump.
