APPARATUS OF ZERO PADDING FOR ENCODING VARIABLE-LENGTH SIGNALING INFORMATION AND METHOD USING THE SAME

摘要

Disclosed are a zero padding apparatus for encoding variable length signaling information and a zero padding method using the same. According to an embodiment of the present invention, the zero padding apparatus comprises: a processor for deciding the number of groups to fill all bits with zero by using difference between the length of an LDPC information bit string and the length of a BCH encoded bit string, for filling all the bits of the groups with zero by selecting the groups through a shortening pattern order, and for filling the BCH encoded bit string in at least a part of the groups not to be filled with zero to generate the LDPC information bit string; and a memory for supplying the LDPC information bit string to an LDPC encoder.
