A parallelized layered QC-LDPC decoder for IEEE 802.11ad [PDF]
2013 IEEE 11th International New Circuits and Systems Conference (NEWCAS), 2013 We present a doubly parallelized layered quasi-cyclic low-density parity-check decoder for the emerging IEEE 802.11ad multigigabit wireless standard. The decoding algorithm is equivalent to a non-parallelized layered decoder and, thus, retains its favorable convergence characteristics, which are known to be superior to those of flooding schedule based ...

Counting short cycles of QC‐LDPC codes in base graph
Electronics Letters, Volume 60, Issue 2, January 2024.Here, a method for using the base matrix to count the number of short cycles of quasi‐cyclic low‐density parity‐check codes is proposed. The time complexity of the proposed algorithm is not directly related to the length of the codes, but only to the number of edges in the base graph. Moreover, as the lifting degree of the codes increases, the proposed

Efficient network for non-binary QC-LDPC decoder [PDF]
2012 IEEE International Symposium on Circuits and Systems, 2012 This paper presents approaches to develop efficient network for non-binary quasi-cyclic LDPC (QC-LDPC) decoders. By exploiting the intrinsic shifting and symmetry properties of the check matrices, significant reduction of memory size and routing complexity can be achieved.

Channel code division multiple access and its multilevel structured LDPC based instantiation [PDF]
, 2008 In this paper, we introduce and outline the concept of Channel Code Division Multiple Access (CCDMA) using a design example based on the recently proposed Multilevel Structured (MLS) LDPC codes. We succeeded in making the memory requirements of the multi-
