Edge Transitive Ramanujan Graphs and Highly Symmetric LDPC Good Codes [PDF]
arXiv, 2011 We present a symmetric LDPC code with constant rate and constant distance (i.e. good LDPC code) that its constraint space is generated by the orbit of one constant weight constraint under a group action. Our construction provides the first symmetric LDPC good codes. This solves the main open problem raised by Kaufman and Wigderson in [4].

End‐to‐end demonstration for CubeSatellite quantum key distribution
IET Quantum Communication, Volume 5, Issue 3, Page 291-302, September 2024.The feasibility of satellite‐based quantum key exchange is investigated using low‐cost compact nano‐satellites. The authors demonstrate the first prototype of system level quantum key distribution aimed at the Cube satellite scenario. It consists of a transmitter payload, a ground receiver and simulated free space channel to verify the timing and ...

High performance short-block binary regular LDPC codes
Alexandria Engineering Journal, 2018 LDPC code shows a good performance with long-block codes. However, certain channels are constrained to use short-block codes due to latency. Therefore, concatenated LDPC codes with iterative decoding is a good choice to get a good performance ...

Tanner
IEEE Access, 2019 Girth plays an important role in the design of low-density parity-check (LDPC) codes. Motivated by the works on the girth of some classes of Tanner quasi-cyclic (QC) LDPC codes, e.g., Tanner (3, 5), (3, 7), (3, 11), and (5, 7) codes, we, in this paper ...

On Multilevel Coding Schemes Based on Non-Binary LDPC Codes [PDF]
arXiv, 2017 We address the problem of constructing of coding schemes for the channels with high-order modulations. It is known, that non-binary LDPC codes are especially good for such channels and significantly outperform their binary counterparts. Unfortunately, their decoding complexity is still large.

LDPC Lattice Codes for Full-Duplex Relay Channels [PDF]
arXiv, 2016 Low density parity check (LDPC) lattices are obtained from Construction D' and a family of nested binary LDPC codes. We consider an special case of these lattices with one binary LDPC code as underlying code. This special case of LDPC lattices can be obtained by lifting binary LDPC codes using Construction A lattices.

Hierarchical and High-Girth QC LDPC Codes [PDF]
, 2011 We present a general approach to designing capacity-approaching high-girth low-density parity-check (LDPC) codes that are friendly to hardware implementation. Our methodology starts by defining a new class of "hierarchical" quasi-cyclic (HQC) LDPC codes that generalizes the structure of quasi-cyclic (QC) LDPC codes. Whereas the parity check matrices of
