Convolutional code decoder and convolutional code decoding method

A convolutional code decoding method which performs decoding, according to a received data and an auxiliary data, to obtain a target data, the convolutional code decoding method comprising:

• performing an error detection operation on the auxiliary data to obtain an error detection data;
• performing channel coding on the auxiliary data and the error detection data to obtain an intermediate data;
• generating a to-be-decoded data according to the received data and the intermediate data;
• and
• decoding the to-be-decoded data by performing the Viterbi decoding operation to thereby obtain the target data.
