1. A method for suppressing noise resulting from inter-symbol interference (ISI) in a receiver for use in a digital data transmission system, comprising the steps of: computing a time domain equalizer at the receiver during initialization between the receiver and a transmitter on a channel; determining a time domain impulse response of the channel; determining a linear time domain equalizer at said receiver; and filtering received data using the linear time domain equalizer to minimize inter-symbol interference at said receiver.
