A method and apparatus is disclosed to overcome the effects of intersymbol
interference during data transmission. Overcoming the effects of
intersymbol interference makes possible higher data transmission rates
for a given error rate. In one embodiment a receiver processing system a
first, second and third filter, such that the second and third filter
comprise feedback filters. Filter coefficients are calculated to reduce
the undesirable effects of the channel, such as intersymbol interference.
A training process occurs to establish the first filter as a mixed phase
filter and the third filter as minimum phase filter. The second filter is
configured based on the transfer function of the channel and one or more
coefficients may be set to a predetermined value.
