Résumé: In this letter, we present a modulo-type Viterbi decoder (VD) which is a combination of modulo operation and VD at the receiver. We describe design rules by which the modulo-type VD and the conventional VD have the same functionality regardless of the shape of the folded-modulo area or the constellation. The modulo-type VD in conjunction with the Tomlinson-Harashima precoder at the transmitter reduces the system complexity significantly as compared to a conventional VD.
