    摘要: A method for detecting data symbols corrupted by intersymbol interference and timing error, comprises calculating a first plurality of state probabilities for received symbols using a forward recursive process on a joint intersymbol interference/timing error (ISI/TE) trellis, calculating a second plurality of state probabilities for the received symbols using a backward recursive process on the joint ISI/TE trellis, and using the first plurality of state probabilities and the second plurality of state probabilities to calculate a posteriori state transition probabilities for the received symbols. An apparatus that performs the method is also disclosed.
