A Soft Decision Descrambler for Guided Scrambling for Optical Disc Systems Employing Low Density Parity Check Codes

Not Accessible

Your library or personal account may give you access


We propose a soft-in-soft-out descrambler for guided scrambling, which realize DC suppression even with simpler RLL codes. The proposed descrambler is realized by simple probability-calculation and can be used with low density parity check codes.
