A Huffman decoder includes a storage module, a receiving module, and a determining module. The storage module stores a target path corresponding to a rare path. The receiving module receives a codeword in a source data stream and acquires corresponding path data for the codeword. The determining module compares the path data and the target path, and determines the codeword as the rare code when the path data and the target path are the same.
