Abstract
The present invention provides an encoding apparatus, comprising means ( ) for generating a checksum for incoming data, means ( ) for constructing frames on the basis of said incoming data and said generated checksum, and means ( ) for multidimensionally coding said frames. Further, the present invention comprises a decoding apparatus for iterative decoding of multidimensionally decoded information, comprising means ( ) for performing at least one decoding iteration on multidimensionally coded information, and means ( ) for checking the decoded information after each decoding iteration and for causing said decoding iteration means ( ) to perform a further decoding iteration on the basis of a checking result. The present invention further comprises the corresponding encoding method and decoding method. The average processing delay and the computational complexity is significantly reduced, since only the required number of iteration steps is adaptively performed in the decoding apparatus.
