ABSTRACT:
A method for interleaving data frames, a forward error correcting device and a modulator including such a device, wherein each data frame to be interleaved is divided into a plurality of words, each containing the same amount of data bytes. An overhead extension is added to the words and additionally, the resulting codewords are applied to an interleave buffer (IB) to be written in matrix-shaped structure of memory cells included in the interleave buffer (IB). This matrix-shaped structure is filled column by column in such a way that each codeword occupies another column. Data bytes are read out of the matrix-shaped structure row by row, as a result of which the data frames are interleaved.
