Algebra-Assisted Construction of Quasi-Cyclic LDPC Codes for 5G New Radio
IEEE Access, 2018 Quasi-cyclic LDPC (QC-LDPC) codes have been accepted as the standard codes of 5G enhanced mobile broadband data channel. These standard codes are designed to support multiple lifting sizes and possess rate-compatible property, which can help adapt ...

LDPC Coded Massive MIMO Systems [PDF]
Entropy, 2019 We design a coded massive multiple-input multiple-output (MIMO) system using low-density parity-check (LDPC) codes and iterative joint detection and decoding (JDD) algorithm employing a low complexity detection. We introduce the factor graph representation of the LDPC coded massive MIMO system, based on which the message updating rule in the JDD is ...

On the Stopping Distance of SA-LDPC Codes by Transversal Designs
IEEE Access, 2018 In this paper, we analyze the size of the smallest stopping set (called the stopping distance) for the parity-check matrix of a superposed array low-density parity-check (SA-LDPC) code for column weights 3 and 4 by using the transversal design (TD ...
