Stochastic EXIT Design for Low-Latency Short-Block LDPC Codes
Toshiaki Koike–Akino, David S. Millar, Keisuke Kojima, Kieran Parsons · 2020
We introduce a stochastic version of extrinsic information transfer (EXIT) chart which accounts for dispersion in finite-length LDPC decoding. The proposed approach can design short LDPC codes systematically, achieving about 1.2 dB gain over recently proposed scattered EXIT design.
