High Rate Reversible LDPC Codes

We investigate algebraic constructions for a class of iteratively encodable low-density parity-check codes suitable for high rate applications. The iterative encoding technique, which is based upon the graphical representation of the code, allows the decoder circuit to be also used for encoding, thus saving circuit area. A method for constructing a (3,6)-regular class of such codes is already k...

A Family of Reversible BCH Codes

Cyclic codes are an interesting class of linear codes due to their efficient encoding and decoding algorithms as well as their theoretical importance. BCH codes form a subclass of cyclic codes and are very important in both theory and practice as they have good error-correcting capability and are widely used in communication systems, storage devices and consumer electronics. However, the dimens...

Reversible Codes and Applications to DNA

The importance of DNA for living creatures is a very well known fact. Furthermore, the rich structure and knowing the role of the structure of DNA has led the researchers to the direction where the structure of DNA can be realized in computing processes and computer related technologies. Recent studies show that DNA can storage data as a big digital memory and can be a good tool for error corre...

Reversible watermarking using two-way decodable codes

Traditional variable length codes(VLC) used in compressed media are brittle and suffer synchronization loss following bit errors. To counter this situation, resynchronizing VLCs(RVLC) have been proposed to help identify, limit and possibly reverse channel errors. In this work we observe that watermark bits are in effect forced bit errors and are amenable to the application of error-resilient te...
