An Architecture for Efficient encoding of Quasi cyclic LDPC codes and its implementation in FPGA
International Conference on Communication Systems and Network Technologies, 2022The Quasi Cyclic LDPC codes are one of the most widely used channel coding technique as they offer low complexity encoding along with parallelism in decoding.

FPGA-Based Quasi-Cyclic LDPC Encoding Algorithm
Asia Communications and Photonics conference and Exhibition, 2022In this paper, an algorithm for quasi-cyclic low-density parity-check code (QC-LDPC) encoding is proposed. The correctness of the algorithm is validated on the FPGA evaluation board. Experimental results show that the encoding delay can be reduced by 3.3

Quasi-cyclic and generalized quasi-cyclic codes and uniqueness of their generators
Discret. Math. Algorithms Appl., 2022In this paper, we use a novel approach to describe generator polynomials of quasi-cyclic (QC) and generalized QC (GQC) codes over finite fields. Our study of QC- and GQC-codes will be general and not only restricted to one-generator codes.

Rate-Compatible Length-Scalable Quasi-Cyclic Spatially-Coupled LDPC Codes
IEEE transactions on broadcastingThe capability of QC-SC-LDPC codes to be employed in broadcasting systems has been studied in previous research. However, the implementation-oriented features such as rate-compatibility and length-scalability for QC-SC-LDPC codes have not been well ...

Entanglement-Assisted Quasi-Cyclic LDPC Codes
Information Theory WorkshopWe provide code constructions along with code properties for a few families of entanglement-assisted (EA) Calderbank-Shor-Steane (CSS) codes derived from quasi-cyclic (QC) low-density parity check (LDPC) codes.

Efficient Construction of Quasi-Cyclic LDPC Codes With Multiple Lifting Sizes
IEEE Communications LettersIn this letter, we present an efficient method for constructing a family of quasi-cyclic low-density parity-check (QC-LDPC) codes specified only by one single exponent matrix that can support multiple lifting sizes.

Quasi-Cyclic Protograph-Based Raptor-Like LDPC Codes With Girth 6 and Shortest Length
International Symposium on Information Theory, 2021We consider multiple-edge QC-LDPC codes with a base matrix of large size. We propose a new method, the degree reduction method, to obtain exponent matrices of these codes which considerably reduces the complexity of the search algorithm.

Construction of Quasi-Cyclic Low-Density Parity-Check Codes based on Quadratic Residue Codes
International Symposium on Medical Information and Communication Technology, 2021Motivated by the success of constructing quasi-cyclic low-density parity-check (QC-LDPC) codes based on Reed-Solomon codes, a construction method for QC-LDPC codes is presented in this paper, using the check matrices of quadratic residues codes. Three QC-
