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…
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…
HARQ Feedback in Spectrum Sharing Networks
Behrooz Makki, Alexandre Graell i Amat, Thomas Eriksson
This letter studies the throughput and the outage probability of spectrum sharing networks utilizing hybrid automatic repeat request (HARQ) feedback. We focus on the repetition tim…
Green Communication via Power-optimized HARQ Protocols
Behrooz Makki, Alexandre Graell i Amat, Thomas Eriksson
Recently, efficient use of energy has become an essential research topic for green communication. This paper studies the effect of optimal power controllers on the performance of d…
On Noisy ARQ in Block-Fading Channels
Behrooz Makki, Alexandre Graell i Amat, Thomas Eriksson
Assuming noisy feedback channels, this paper investigates the data transmission efficiency and robustness of different automatic repeat request (ARQ) schemes using adaptive power a…
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…
