摘要： A device such as a worker, window-size and iteration control unit (WWICU) is proposed. The WWICU determines processing, iteration, and window information based on format information indicative of one or more formats to be processed by a decoding process. The processing information may include a number of parallel workers, the iteration information may include a number of half-iterations, and the window information may include a window size to be used in the decoding process. The WWICU then determines time information including a total cycle count based on the processing information, the iteration information, and the window information. In response to determining that the total cycle count is not beyond a threshold value, the WWICU may transmit configuration information including the processing, iteration, and window information to a device, such as a turbo decoding device, configurable to perform the decoding process based on the configuration information.

摘要： An iterative decoder for decoding a code block comprises a computation unit configured to perform forward and backward recursions over a code block or a code sub-block in each decoding iteration. A first forward/backward decoding scheme is used in a first iteration and a second forward/backward decoding scheme is used in a second iteration. The first and second decoding schemes are different in view of forward and backward processing.

摘要： In a method of decoding data symbols into codewords, reliability information of the data symbols is provided. A first group of symbols from a first set of groups of symbols is selected, wherein the first set of groups of symbols is defined by at least a first parity-check of a parity-check matrix of a linear block code which has been used to encode the data symbols. The selection is based on the reliability information. A second group of symbols from a second set of groups of symbols is selected, wherein the second set of groups of symbols is defined by at least a second parity-check of the parity-check matrix. The selection is based on the selected first group of symbols and the reliability information. At least a part of the codeword is composed on the basis of the first group of symbols and the second group of symbols.

摘要： A method for retransmission of erroneous data in a communications system includes receiving data blocks at a receiver that have been generated in a transmitter by the use of an error correcting code. The received data blocks are decoded by a linear programming algorithm. One or more symbols in the decoded data block are identified by subjecting the symbols in the decoded data block to an integrality criterion. A retransmission of a part of the data block based on the one or more identified symbols is then initiated.

摘要： A device such as a turbo decoding device is proposed in which an intermediate buffering device including an address buffering device and an element buffering device is communicatively coupled to a plurality of processing devices and a memory device. During a cycle of a parallel decoding process, the intermediate buffering device receives, from two different processing devices, first and second address information respectively corresponding to first and second elements of a code sequence stored in the memory device. During the cycle, the intermediate buffering device transmits a request for the first element to the memory device based on the first address information and stores the second address information in the address buffering device. Subsequently, during the cycle, the intermediate buffering device receives first element information corresponding to the first element from the memory device and stores the received first element information in the element buffering device.
