A Reduced-Complexity Projection Algorithm for ADMM-based LP Decoding

10 Jan 2019 Gensheimer Florian Dietz Tobias Kraft Kira Ruzika Stefan Wehn Norbert

The Alternating Direction Method of Multipliers has recently been adapted for Linear Programming Decoding of Low-Density Parity-Check codes. The computation of the projection onto the parity polytope is the core of this algorithm and usually involves a sorting operation, which is the main effort of the projection... (read more)
