Abstract: This paper studies the design of protograph low-density parity-check (PLDPC) coded sparse code multiple access (SCMA) systems with power-imbalanced multi-level decoding (PI-MLD) scheme.

LDPC codes, how small random parity sets unlocked reliable communication
Every transmission channel loses bits, and the real puzzle is how to recover them without slowing everything down. This video traces the elegant logic behind low-density parity-check codes, from ...
AI thrives on data but feeding it the right data is harder than it seems. As enterprises scale their AI initiatives, they face the challenge of managing diverse data pipelines, ensuring proximity to ...
Abstract: In this paper, we propose a new class of globally-coupled low-density parity-check (GC-LDPC) codes, referred to as variable node (VN) based tail-biting (TB) GC-LDPC codes. Unlike ...
