Patent ID: 8196015

Claim:
A method for receiving a data block, the method comprising the following steps: performing line decoding of a signal carrying a transmission block, wherein the transmission block has a first transmission sub-block consisting of a sub-block of the data block and first check data and a second transmission sub-block consisting of a second sub-block of the data block and second check data, outputting results of the line decoding after a soft decision for each received bit of the transmission block, performing soft-input soft-output channel decoding of the transmission block, wherein an output reliability value which specifies the reliability value of the decision of the channel decoder for the correctness of the relevant bit is output as the result of the decoding for each received bit, verifying a correct reception of the first and second sub-blocks based on the first and of the second check data, respectively, if necessary, performing error correction with respect to the first and/or second transmission sub-blocks, if the performance of error correction was required for both the first and the second of the transmission sub-blocks and the performance of the error correction for one of the first and second transmission sub-blocks is successful and fails for another one of the first and second transmission sub-blocks, increasing the output reliability values which are allocated to the bits of the one of the transmission sub-blocks and repeated performance of the channel decoding, wherein the increased output reliability values allocated to the bits of the one of the transmission sub-blocks are used as input reliability values for the repeated performance of the channel decoding, checking the correct reception of the other one of the transmission blocks after performance of the repeated channel decoding and, if necessary, repeating the performance of the error correction with respect to the other one of the data transmission blocks.
