Optimized interleaving of digital signals

摘要

A method is described for changing the order of bytes of digital signals transmitted in frames according to a cyclic rotation of the bytes and for changing the frame format. This method can advantageously be used in a concatenated coding scheme, e.g a serial concatenation of two Reed-Solomon codes, to achieve the best trade off between coding gain and line bit rate. The disclosed interleaving method is applicable to optical transport networks. <IMAGE>
