Low-density parity-check (LDPC) codes represent one of the most effective error-correcting schemes available, approaching Shannon’s theoretical limit whilst maintaining a relatively low decoding ...

At present, low density parity check code (LDPC) has been widely used in channel coding and decoding because of its excellent performance, but with the increase of code length, the complexity of ...

The increasing popularity of optical communication systems emphasizes the need for effective errorcorrection solutions, including high-efficiency hardware decoder designs and codes with strong ...

The Decoding Algorithm This article focuses on a special class of LDPC codes called block-structured LDPC codes, which have been adopted by many new wireless standards (IEEE 802.11n, IEEE 802.16e). As ...

AR4JA LDPC decoder uses a Min-Sum algorithm to perform decoding. The min-Sum algorithm is an iterative algorithm that progresses to convergence through two updates: check node update and variable node ...

The DVB-S2/S LDPC/BCH decoder a silicon proven IP extracted from production chips has an octal input interface and a single output interface. The data coming from the 8 demodulators are multiplexed ..

EPIC developed FEC algorithms in all three major code families—Turbo, LDPC and Polar codes. These code families have all been prominent technologies in 3G, 4G and 5G, and will continue to be ...

The need for higher densities and packing more bits into a single cell have pushed up the number of errors that occur. Low-Density Parity Check (LDPC) error ...

Essentially LDPC codes are a class of FEC codes that are based on a sparse matrix parity check. The challenge is that optimal decoding of LDPC is an NP-complete problem.

Technical Terms LDPC code: An error-correcting code with a sparse parity-check matrix that approaches Shannon’s capacity limit with efficient iterative decoding algorithms.
