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 ...

5G‐coded fluid antenna multiple access over block fading channels
Electronics Letters, Volume 61, Issue 1, January/December 2025.This letter investigates the use of 5G New Radio (NR) Modulation Coding Scheme (MCS) for FAMA systems to improve its connectivity over block fading channels. In particular, we propose an iterative decoding receiver with iterative interference covariance estimation, designed explicitly for slow fading channels.

Error Exponents of Low-Density Parity-Check Codes on the Binary Erasure Channel
, 2006 We introduce a thermodynamic (large deviation) formalism for computing error exponents in error-correcting codes. Within this framework, we apply the heuristic cavity method from statistical mechanics to derive the average and typical error exponents of ...

A Non‐Binary Dual Cascade Polar Codes Construction and Low‐Complexity SCL Decoding
Electronics Letters, Volume 61, Issue 1, January/December 2025.First, we design an error‐correction approach including two cascade non‐binary polar coding (NB‐CPolar) structures and a cyclic redundancy check (CRC) code. Second, we propose a low‐complexity decoding algorithm based on non‐binary successive cancellation list (NB‐LSCL) decoding.
