Abstract: Structured LDPC, such as RA, IRA, ARA, QC-LDPC etc., are some important LDPC codes, these codes usually have very good performance and facilitate the implementation of encoding and decoding ...

A new technique for efficient encoding of LDPC codes based on the known concept of Approximate Lower Triangulation (ALT) is introduced. The greedy permutation algorithm is presented to transform ...

Abstract: In this paper, we present a class of QC-LDPC codes with continuously variable length (CVL), which can be encoded in linear time. The method combines CVL codes [1] with approximate lower ...

Computex 2014 - Error rates are increasing as NAND manufacturers shrink lithography. This requires SSD controller innovation to provide stronger error correction ...

ABSTRACT: In order to solve the problem that the original decoding algorithm of multi-band LDPC codes is high and is not conducive to hardware implementation, two simplified decoding algorithms for ...

For communication designers, especially those in the networking and wireless field, the Shannon limit can be seen as the Holy Grail. And, since being first defined in ...

Our LDPC encoding and decoding IP for the 3GPP New Radio uplink and downlink data channel includes the entire processing chain, to provide quick and e ...

HLS methodology allows the hardware design to be completed at a higher level of abstraction such as C/C++ algorithmic description. This provides significant time and cost savings, and paves the way ...
