Abstract
The invention discloses a convolutional code decoder and a convolutional code decoding method. The convolutional code decoder and the convolutional code decoding method of the present invention perform decoding using predictive information, and therefore can demodulate/decode signals more quickly. Earlier completion of demodulation/decoding of signals can terminate the operation earlier and thereby achieve the effect of power savings. The convolutional code decoder performs decoding according to received data and auxiliary data to obtain target data, and includes a first error detection data generation circuit, a channel coding circuit, a first selection circuit, a first Viterbi decoding circuit, a second error detection data generation circuit, a comparison circuit, a second selection circuit, and a second Viterbi decoding circuit.
