Descriptors are used, which combine the code words of a transmission block of the same correctability into a subset, and which describe the size of the subset as well as the difference in the correctability of the previously concerned subset.

Method for correcting errors in a packet-oriented data transmission

Individual data packets are transmitted together with information about the end of a respective data packet, without padding, and then virtual padding is effected for generating redundant packets. At the receiver, the data packets are obtained using the information about the respective end of packet if no packet was lost, and are only expanded by padding if a packet has been lost and can be reconstructed by one or more redundant packets.

Method and apparatus for protecting against packet losses in packet-oriented data transmission

A method is provided for channel decoding a data stream containing useful data and redundant data, the data stream exhibiting at least one known source-coded errored bit sequence which identifies a pre-determined position within the data stream, wherein the data stream is channel decoded, the source-coded errored bit sequence is determined from the channel-decoded data stream, and the data stream is again channel decoded taking into consideration the detected source-coded errored bit sequence.

An adaptive abort criterion in iterative decoding of transmitted, multi-dimensionally encoded information employs the relative entropy, approximations of the relative entropy or quantities similar thereto as criterion for the change in the weighted decisions of successive iteration sub-steps. When an iteration sub-step does not produce a change of the relative entropy lying above a predetermined threshold, then the iterative decoding is aborted.

Method and arrangement for determining an adaptive abort criterion in

Method for protected transmission of data with multi-component coding, whereby a non-uniform error protection is achieved by selection of important bits or bit sequences from an information sequence (I), the bit sequences being supplied to further component coders (COD1 through COD3).
