Abstract: 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.

Abstract: The present disclosure relates to a method for the determination of an antenna weighing factor for base stations of a cellular radio network, wherein a radio link to a terminal can be established simultaneously via several base stations which respectively transmit in a parallel manner via several transmission paths from various antennas to the terminal. The terminal respectively determines channel coefficients for the transmission paths for the associated base stations and determines an antenna weighting factor using the channel coefficients and transmits the coefficients to the base stations. A transmission quality value of a transmission channel between the respective base station and the terminal is determined for the individual base stations and the channel coefficients of the individual base stations are prioritized and taken into account using the determined antenna weighting factor.

Abstract: 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.

Abstract: 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.

Abstract: The data stream contains useful data and redundant data and at least one source-coded error-containing bit sequence that characterizes a given position within the data stream. The source-coded, error-free bit sequence is known by the channel decoder. The data stream is channel-decoded and the source-coded, error-containing bit sequence is determined from the channel-coded data stream. The data stream is once again channel-decoded, wherein the data stream is once again channel decoded taking into account the detected source coded, error-containing bit sequence.

Abstract: 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.

Abstract: 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).
