摘要: In a channel encoder comprising a dk-encoder stage and a precoding stage, obeyance of a repeated minimum transition runlength constraint is achieved because, between the dk-encoder and the precoder, data are passed through an RMTR encoder which replaces occurrences of a forbidden pattern by a current replacement pattern having the same length as the forbidden pattern. By appropriately selecting current replacement patterns from a predefined set of two different replacement patterns, DC-control can be achieved for the encoder output. The corresponding decoder is described, which also employs pattern replacement.

摘要: A method for bit recovery in an asymmetric data channel, the method comprising the steps of: providing a non-linear equalization filter with two coefficient sets; using the non-linear equalization filter with a first coefficient set for compensating defects of a first type of transition between different storage states; and using the non-linear equalization filter with a second coefficient set for compensating defects of a second type of transition between different storage states.
