Techniques to decode tail biting convolutional code are disclosed. A plurality of sets for a trellis may be determined. Each set may include a first stage and a second stage of the trellis. Path metrics for each state in a set may be determined when the first stage and the second stage have a same state. The path metrics may be compared to determine a state with a minimum path metric. Bits from the state with the minimum path metric may be output. Other embodiments are described and claimed.
