摘要： The invention relates to low density parity check decoding. A method for decoding an encoded data block is described. Encoded data block comprising data sub-blocks are stored. Decoding is performed in a pipelined manner using an irregular, block-structured parity check matrix, where at least two data sub-block matrices of the parity check matrix are read from and written in each of a plurality of clock cycles. The reading and writing of the data sub-blocks is evenly distributed between at least two area of a memory. The decoding is performed with shift values which eliminate cycles at or below a predetermined threshold length. An apparatus, computer program product and device are also described.

摘要： A source sends an encoded data block during a first time interval to a destination and to a relay. The source sends additional parity bits for the encoded data block during a second time interval. The relay partially decodes that encoded data block to a process-defined end point (typically only a partial decoding), such as a fixed number of decoding iterations. After partial decoding the relay forms a modified data block having corrected information bits and the parity bits of the block it received, and sends the modified data block to the destination, during the second time interval. The destination decodes to a results-defined end point the modified data block it received from the relay using the additional parity bits it received from the source. If that end-point cannot be reached, the destination may begin anew decoding the original encoded data block it received from the source.
摘要翻译：源在第一时间间隔期间将编码数据块发送到目的地和中继。源在第二时间间隔期间为编码数据块发送附加奇偶校验位。继电器将编码数据块部分地解码为过程定义的终点（通常只是部分解码），例如固定数量的解码迭代。在部分解码之后，继电器形成具有校正信息位的修正数据块及其接收的块的奇偶校验位，并在第二时间间隔期间将修改的数据块发送到目的地。目的地使用从源接收到的附加奇偶校验位将从接收器接收到的修改的数据块解码为结果定义的终点。如果无法达到该终点，目的地可能会重新对从源接收到的原始编码数据块进行解码。
