摘要
The disclosure relates to a decoding device, comprising: a receiver configured to provide a sequence of information bits comprising context redundancy information, wherein the sequence of information bits is encoded based on a predefined channel code; a trellis generation logic configured to generate a plurality of trellis states based on the sequence of information bits and the channel code; a trellis reduction logic configured to reduce the plurality of trellis states by at least one trellis state based on the context redundancy information; and a decoder configured to decode the sequence of information bits by using a metric based on the reduced number of trellis states.
