Abstract
A data dependent scrambler for a communications channel that receives a user data sequence including N symbols and host cyclic redundancy check (CRC) bits comprises a data buffer that receives the user data sequence and the host CRCbits. A seed finder generates a scrambling seed that is dependent upon the symbols in the user data sequence. A first scrambler receives the user data sequence from the data buffer and the scrambling seed from the seed finder and generates the scrambled user data sequence. A second scrambler generates a difference sequence that is based on the user data sequence and the scrambled user data sequence.
