Energy-Efficient Soft-Assisted Product Decoders
Christoffer Fougstedt, Alireza Sheikh, Alexandre Graell i Amat +2
We implement a 1-Tb/s 0.63-pJ/bit soft-assisted product decoder in a 28-nm technology. The decoder uses one bit of soft information to improve its net coding gain by 0.2 dB, reachi…
On Low-Complexity Decoding of Product Codes for High-Throughput Fiber-Optic Systems
Alireza Sheikh, Alexandre Graell i Amat, Gianluigi Liva +2
We study low-complexity iterative decoding algorithms for product codes. We revisit two algorithms recently proposed by the authors based on bounded distance decoding (BDD) of the…
Iterative Bounded Distance Decoding of Product Codes with Scaled Reliability
Alireza Sheikh, Alexandre Graell i Amat, Gianluigi Liva
We propose a modified iterative bounded distance decoding of product codes. The proposed algorithm is based on exchanging hard messages iteratively and exploiting channel reliabili…
