摘要： A method and device for decoding a plurality of packets of same data. Each packet is encoded using a product code. An encoded packet comprises data blocks is organized into rows and columns. Each of the rows and columns has a respective error detecting code. For a data packet, Erroneous row and column data are detected by their associated error detecting code. In the data packet, a potentially erroneous data block belonging to a row and a column of data blocks both having been detected as erroneous is detected. In another data packet of the same data, a non-erroneous data block corresponding to the identified potentially erroneous data block is determined. The data block is determined as non-erroneous if it belongs to at least one row or column of data having been detected as non-erroneous. The identified potentially erroneous block is replaced with the determined non-erroneous block.
