Zusammenfassung:	A method and system for adaptive prefiltering of a signal for transmission is described. The method includes determining a reference starting value of coefficients for a receiver equalizer filter, receiving an indication of a change in channel characteristics based on a signal received at the receiver equalizer filter, computing coefficients for an adaptive filter based on the reference starting value and the change in channel characteristics, setting the coefficients of the adaptive filter equal to the computed coefficients, and filtering a signal for transmission through the adaptive filter.
