A receiver ( 1 ) has an equalizer ( 2, 4, 5 ) which introduces inter symbol interferance (ISI) in a controlled manner and low pass filters to reduce noise. The ISI is introduced and the noise is reduced by a filter ( 4 ) in an adaptation path. A trellis decoder ( 3 ) of the receiver ( 1 ) removes the ISI to avoid propagation error. It does this in front end modules ( 20 ), outside of its critical path. There is a better decoder performance because noise is smaller.
