Method for error correction in packet-oriented data transmission with transmission blocks that are better determined by descriptors
View Patent ↗Additional descriptors are used which, unlike known descriptors, only describe the size of the subset and the difference in correction capability. The additional descriptors also identify a defined separation between a signaling block and at least one data block, in addition to the positions of the filler bits within the transmission block or data block.
1. A method for error correction in packet-oriented data transmission, comprising:
defining transmission blocks by descriptors;
creating a set of code words for each transmission block, the set of code words relating to correction capabilities and an error protection profile for the respective transmission block;
forming descriptors for each transmission block to directly or indirectly describe immediately sequenced code words within a subset having the same correction capability, the descriptors directly or indirectly describing the size and correction capability of subsets; and
dividing the transmission block into sub-data blocks each having the same error correction capability such that the end of each sub-data block is marked by a respective end of a data block descriptor which has a reserved descriptor value.
2. The method according to claim 1 , further comprising inserting a filler bit descriptor for each sub-block, which filler bit descriptor specifies the number of filler bits at the end of the respective data block the filler bit descriptor being inserted after the end of the data block descriptor.
3. The method according to claim 2 , wherein
the transmission block is divided into a signaling block containing the descriptors and into separate sub-data blocks, and
a signaling descriptor, which specifies the number of rows required for the signaling block, is inserted at a first position in the signaling block.
4. A method according to claim 3 ,
whereby all descriptors have the same format.
5. The method according to claim 1 , wherein
the transmission block is divided into a signaling block containing the descriptors and into separate sub-data blocks, and
a signaling descriptor, which specifies the number of rows required for the signaling block, is inserted at a first position in the signaling block.
6. A method according to claim 1 ,
whereby all descriptors have the same format.
7. A method for error correction in packet-oriented data transmission, comprising:
dividing a transmission block into sub-data blocks each having the same error correction capability, each sub-data block containing at least one code word; and
using descriptors to describe the length of each sub-data block and to describe how the error correction capability of each sub-data block differs from a neighboring sub-data block, the descriptors not providing a full description of the error correction capability of individual code words.
