Rate-Adaptive Protograph-Based MacKay-Neal Codes
Ayman Zahr, Emna Ben Yacoub, Balázs Matuz +1
Rate-adaptive MacKay-Neal (MN) codes based on protographs are analyzed. The code construction employs an outer distribution matcher (DM) to adapt the rate of the scheme. The DM is…

Rate-Adaptive Spatially Coupled MacKay-Neal Codes with Thresholds Close to Capacity
Ayman Zahr, Gianluigi Liva
We analyze by density evolution the asymptotic performance of rate-adaptive MacKay-Neal (MN) code ensembles, where the inner code is a protograph spatially coupled (SC) low-density…
