A Low-Complexity Detector for Memoryless Polarization-Multiplexed Fiber-Optical Channels
Christian Häger, Lotfollah Beygi, Erik Agrell +3
A low-complexity detector is introduced for polarization-multiplexed M-ary phase shift keying modulation in a fiber-optical channel impaired by nonlinear phase noise, generalizing…
A New Look at Dual-Hop Relaying: Performance Limits with Hardware Impairments
Emil Björnson, Michail Matthaiou, Mérouane Debbah
Physical transceivers have hardware impairments that create distortions which degrade the performance of communication systems. The vast majority of technical contributions in the…
Quasi-Static Multiple-Antenna Fading Channels at Finite Blocklength
Wei Yang, Giuseppe Durisi, Tobias Koch +1
This paper investigates the maximal achievable rate for a given blocklength and error probability over quasi-static multiple-input multiple-output (MIMO) fading channels, with and…
Threshold Saturation for Nonbinary SC-LDPC Codes on the Binary Erasure Channel
Iryna Andriyanova, Alexandre Graell i Amat
We analyze the asymptotic performance of nonbinary spatially-coupled low-density parity-check (SC-LDPC) code ensembles defined over the general linear group on the binary erasure c…
Achievable Rates for Four-Dimensional Coded Modulation with a Bit-Wise Receiver
Alex Alvarado, Erik Agrell
We study achievable rates for four-dimensional (4D) constellations for spectrally efficient optical systems based on a (suboptimal) bit-wise receiver. We show that PM-QPSK outperfo…

Soft metrics and their Performance Analysis for Optimal Data Detection in the Presence of Strong Oscillator Phase Noise
Rajet Krishnan, M. Reza Khanzadi, Thomas Eriksson +1
In this paper, we address the classical problem of maximum-likelihood (ML) detection of data in the presence of random phase noise. We consider a system, where the random phase noi…
Constellation Optimization in the Presence of Strong Phase Noise
Rajet Krishnan, Alexandre Graell i Amat, Thomas Eriksson +1
In this paper, we address the problem of optimizing signal constellations for strong phase noise. The problem is investigated by considering three optimization formulations, which…
