ABSTRACT:
A sequential decoding method and a decoding apparatus are provided. According to the method, an open stack is adopted for storing a plurality of paths. When the codeword generated by an internal decoder in the decoding apparatus is incorrect, a codeword is generated again by using the paths stored in the open stack. Accordingly, the complexity of decoding is reduced.
