Abstract

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.
