Stochastic EXIT Design for Low-Latency Short-Block LDPC Codes

Not Accessible

Your library or personal account may give you access

Abstract

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.
