Abstract :
A method is demonstrated for modifying majority-logic convolutional decoders fur use in type-1 hybrid-ARQ protocols. Majority-logic decoders generate reliability information in the form of orthogonal sets of parity check sums. The modified decoder uses this information to identify received packets whose decoded data may be unreliable and to request their retransmission
