摘要
A modified classical Viterbi decoder which can take extrinsic information and output hard decisions. A modified Viterbi decoder is provided comprising a branch metric unit, the unit having a calculator; and a processor adapted to compute a revised branch metric by combining the initial branch metric and an additional weight parameter. The modified classical Viterbi decoder computes a branch metric by summing an initial branch metric and the additional weight parameter.
