Abstract

See full text

In a Viterbi Algorithm decoder (204) as used to decode convolutionally encoded information, reliability information is developed for various path discard decisions made within the Viterbi Algorithm. These decisions are made for discard opportunities that impact one or more error detection windows (601). Based upon these metrics, a reliability factor sequence can be provided and compared against a fixed (or varying) threshold. When unreliability appears, appropriate action can be taken. For example, all of the information can be discarded, or only certain portions of the information can be discarded, as appropriate to the particular application.
