A Universal Efficient Circular-Shift Network for Reconfigurable Quasi-Cyclic LDPC Decoders

IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2022
Quasi-cyclic low-density parity-check (QC-LDPC) codes for modern communication standards usually have multiple code rates and block lengths. Therefore, reconfigurable LDPC decoders have received widespread attention, which require circular-shift networks

Quasi-cyclic Goppa codes

2000 IEEE International Symposium on Information Theory (Cat. No.00CH37060), 2002
In this paper, we construct quasi-cyclic Goppa (or related) codes. Some of these codes reach the parameters of best known codes. Generally, there is no known quasi-cyclic code for these lengths and dimensions.

Using Minors to Construct Generator Matrices for Quasi-Cyclic LDPC Codes

International Symposium on Information Theory, 2022
This paper gives a simple method to construct generator matrices with polynomial entries (and hence offers an alternative encoding method to the one commonly used) for all quasi-cyclic low-density parity-check (QC-LDPC) codes, even for those that are ...
