Abstract

A digital equalizer for interpreting a digital signal including convolutionally encoded symbols and synchronization symbols outside the convolutional code comprises a combined trellis encoder and DFE. The synchronization symbols are re-inserted into the input of the DFE in order to restore time domain continuity created by removal of the synchronization symbols.
