COMPARATIVE ANALYSIS OF LDPC AND BCH CODES ERROR-CORRECTING CAPABILITIES
Information and Telecommunication Sciences, 2014 The error-correcting capabilities of regular LDPC (Low Density Parity Check) codes and BCH (Bose-Chaudhuri-Hocquenguem) codes are examined. The qualitative analysis and the quantitative assessment of error-correcting abilities are performed for LDPC ...

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This article evaluates the performance of a data‐driven 5G OFDM‐based passive radar under dynamic modulation orders and low‐density parity‐check (LDPC) coding for integrated sensing and communication (ISAC) applications. Simulations demonstrate that maintaining standard communication reliability via LDPC coding minimises signal reconstruction errors ...

Adaptive Offset Min‐Sum Decoder for 5G‐NR BG2 LDPC Codes Using Genetic Algorithm
Applied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.This paper proposes a more efficient resource‐constrained decoding algorithm for Adaptive Offset Min‐Sum (A‐OMS) low‐density parity check (LDPC) optimized decoder parameters in fifth‐generation New Radio (5G‐NR) Base Graph 2 codes (BG2). To curb the challenge of observing the all‐time finest offset to use the irregular BG2 structure, a genetic ...

Multilevel structured low-density parity-check codes for AWGN and Rayleigh channels
, 2010 We propose a novel class of protograph low-density parity-check (LDPC) codes having a combinatorial rather than a random structure, which are termed multilevel-structured (MLS) LDPC codes. It is demonstrated that they posses a strikingly simple structure
