<p>A Viterbi equalizer (6) for signals with bit alternating modulation is characterized by a number of channel estimation units (8a, 8b) corresponding to the number of modulation states of the bit alternating modulation, the channel estimation units (8a, 8b) being operated in alternating order. An optical receiver comprises such a Viterbi equalizer (6), the latter being used in an optical transmission system. A Viterbi equalization method for signals with bit alternating modulation comprises the steps of: generating a separate channel estimation for each modulation state of the bit alternating modulation, and performing the Viterbi equalization using the channel estimations in alternating order.</p> |
