Majority-Logic Decoding

Majority-logic decoding of convolutional codes, proposed by Massey [308], is a sub-optimum but simple decoding scheme that allows a high-speed implementation. Its performance is sub-optimum since each of its decoding decision is based only on one output constraint length of received bits. This “limited vision” is not there in Viterbi or sequential decoding which, in principle, consider the entire received sequence before making decoding decisions.
