Probabilistic Eigenvalue Shaping for Nonlinear Fourier Transform Transmission
Andreas Buchberger, Alexandre Graell i Amat, Vahid Aref +1
We consider a nonlinear Fourier transform (NFT)-based transmission scheme, where data is embedded into the imaginary part of the nonlinear discrete spectrum. Inspired by probabilis…
Block-Diagonal and LT Codes for Distributed Computing With Straggling Servers
Albin Severinson, Alexandre Graell i Amat, Eirik Rosnes
We propose two coded schemes for the distributed computing problem of multiplying a matrix by a set of vectors. The first scheme is based on partitioning the matrix into submatrice…
Achieving Maximum Distance Separable Private Information Retrieval Capacity With Linear Codes
Siddhartha Kumar, Hsuan-Yin Lin, Eirik Rosnes +1
We propose three private information retrieval (PIR) protocols for distributed storage systems (DSSs) where data is stored using an arbitrary linear code. The first two protocols,…
Successive Cancellation Decoding of Single Parity-Check Product Codes
Mustafa Cemil Coşkun, Gianluigi Liva, Alexandre Graell i Amat +1
We introduce successive cancellation (SC) decoding of product codes (PCs) with single parity-check (SPC) component codes. Recursive formulas are derived, which resemble the SC deco…
Probabilistic Amplitude Shaping with Hard Decision Decoding and Staircase Codes
Alireza Sheikh, Alexandre Graell i Amat, Gianluigi Liva
We consider probabilistic amplitude shaping (PAS) as a means of increasing the spectral efficiency of fiber-optic communication systems. In contrast to previous works in the litera…
Probabilistically-Shaped Coded Modulation with Hard Decision Decoding for Coherent Optical Systems
Alireza Sheikh, Alexandre Graell i Amat, Gianluigi Liva
We consider probabilistic shaping to maximize the achievable information rate of coded modulation (CM) with hard decision decoding. The proposed scheme using binary staircase codes…
