1. A method for processing data received from a communications channel comprising the computer-implemented steps of:
receiving, from the communications channel, received data that is based upon both modulated data and distortion introduced by the communications channel, wherein the modulated data is the result of original data modulated onto one or more carriers;
equalizing the received data using an equalizer to generate equalized data, wherein the equalizer uses an algorithm with a set of one or more coefficients selected to account for a frequency domain response of the equalizer and to reduce the distortion introduced by the communications channel; and
recovering an estimate of the original data by demodulating the equalized data.
