Abstract
A reference data sequence is transmitted and applied to a first automatic equalizer which is arranged in a reference channel. The transmitted reference data is used to establish an initial equalization of the first automatic equalizer. On the other hand, the transmitted reference data sequence is scrambled and is used to establish an initial equalization of another automatic equalizer to which another data sequence obtained by scrambling the reference data sequence is transmitted.
