Random-Access LDPC Codes

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


New types of LDPC codes motivated by practical storage applications are presented. LDPCL codes (suffix ’L’ stands for locality) can be decoded locally at the level of subblocks that are much smaller than the full code block, thus providing fast random access to the coded information. The same code can also be decoded globally using the entire code block (as usual), for increased data reliability. We present constructions of LDPCL and spatially-coupled LDPCL codes that enable random access, and we exemplify their benefits over ordinary LDPC codes.
