Machine learning assisted adaptive LDPC coded system design and analysis
IET Communications, Volume 18, Issue 1, Page 1-10, January 2024.A learning‐aided adaptive modulation and coding system for short block length scenarios are proposed. This is applicable to Internet of Things and URLLC cases. Abstract This paper proposes a novel machine learning (ML) assisted low‐latency low density parity check (LDPC) coded adaptive modulation (AM) system, where short block‐length LDPC codes are ...
