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…
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…
Calculation of the Performance of Communication Systems from Measured Oscillator Phase Noise
M. Reza Khanzadi, Dan Kuylenstierna, Ashkan Panahi +2
Oscillator phase noise (PN) is one of the major problems that affect the performance of communication systems. In this paper, a direct connection between oscillator measurements, i…
