<p><P>PROBLEM TO BE SOLVED: To provide an encoder and decoder for zigzag codes for providing enhanced performance. <P>SOLUTION: An encoder 100 further comprises a zigzag encoder 120 for calculating a redundancy bit for a current segment, wherein a redundancy bit of an earlier segment in the order is used when calculating the redundancy bit for the current segment. The encoder 100 comprises an interleaver 130 for interleaving the bits of the plurality of segments using an interleaving rule to obtain an interleaved version and an output codeword constructor 140 for constructing the output codeword using an input codeword or the interleaved version thereof and a set of redundancy bits generated by the zigzag encoder 120 fed by the interleaved version. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
