Bounds on the capacity of the bit-shift magnetic recording channel

S. Shamai, E. Zehavi
1991 IEEE Transactions on Information Theory  
Runlength-limited (RLL) sequences, known also as ( d , k ) codes, are widely used in magnetic recording systems [l], [2], [5]-[7], [lo], [ll] (and references therein).  ...  The commonly used RLL sequences do not usually possess significant error-correcting capabilities [ 111 and therefore they are unable to cope efficiently with the channel impairments.  ...  A single peak shift evidently causes at most two consecutive errors, thus codes with short burst correction properties may turn efficient in this scenario.  ...

Exploiting the CRC-CCITT code on the binary erasure channel

Eirik Rosnes, Guang Yang, Oyvind Ytrehus
2010 2010 6th International Symposium on Turbo Codes & Iterative Information Processing  
Due to the properties of inductive coupling, the communication over the inductively coupled channel has synchronization loss problems in addition to other classical channel errors.  ...  A passive RFID system transfers energy together with information by means of inductive coupling. Coding schemes design for inductively coupled channels is the main task of this work.  ...  The timing errors that are induced by bit-shift channels can be detected and corrected by window-shift decoding, or a combination of window-shift decoding and other error correcting codes. . 4 L E V  ...
