    摘要: A turbo decoder includes a state transition probability computing unit which obtains a state transition probability from data, a flag, and a priori probability from a previous stage, an alpha and beta metric computing unit which obtains an alpha metric and a beta metric from the state transition probability by computing a plurality of processes concurrently in a time sequence, and a normalization unit which obtains decoded data and a priori probability for a next stage based on the state transition probability obtained by the state transition probability computing unit and on the alpha metric and the beta metric obtained by the alpha and beta metric computing unit.
