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.

A High Throughput Implementation of QC-LDPC Codes for 5G NR

IEEE Access, 2019
Quasi-cyclic low-density parity-check (QC-LDPC) codes are the choice for data channels in the fifth generation (5G) new radio (NR). At the transmitter side, code bits from the QC-LDPC encoder are delivered to the rate matcher.

Jointly designed quasi-cyclic LDPC-coded cooperation with diversity combining at receiver

International Journal of Distributed Sensor Networks, 2020
This correspondence proposes a jointly-designed quasi-cyclic (QC) low-density parity-check (LDPC)-coded multi-relay cooperation with a destination node realized by multiple receive antennas.

Tanner $(J,L)$ Quasi-Cyclic LDPC Codes: Girth Analysis and Derived Codes

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 ...

Optimized puncturing distributions for irregular non-binary LDPC codes

, 2010
In this paper we design non-uniform bit-wise puncturing distributions for irregular non-binary LDPC (NB-LDPC) codes. The puncturing distributions are optimized by minimizing the decoding threshold of the punctured LDPC code, the threshold being computed ...

Design of rate-compatible low-density parity-check codes for type-II hybrid ARQ systems

Tongxin xuebao, 2006
The design of powerful rate-compatible low-density parity-check codes（RC-LDPC）was constructed in zigzag structure for type-II hybrid ARQ systems.The generalized PEG algorithm was used in the process of constructing RC-LDPC codes to improve the ...

LDPC DropConnect

, 2023
Machine learning is a popular topic that has become a scientific research tool in many fields. Overfitting is a common challenge in machine learning, where the model fits the training data too well and performs poorly on new data. Stochastic regularization is one method used to prevent overfitting, by artificially constraining the model to be simpler ...
