ABSTRACT:
A multi-rate encoder and decoder system is disclosed. The multi-rate encoder and decoder system is capable of operating with a mother code or a subset code of the mother code and includes a trellis encoder having a set of inputs and a set of outputs corresponding to the mother code and a select unit capable of removing the set of inputs into the trellis encoder that correspond to the mother code but not the subset code prior to encoding. The multi-rate encoder and decoder system further includes a decoder having a set of decoder inputs and a set of decoder outputs corresponding to the mother code and a decoder select unit capable of ignoring transitions in the trellis code produced by the encoder that belong to the mother code but not to the subset code.
