Capacity Bounds under Imperfect Polarization Tracking
Mohammad Farsi, Magnus Karlsson, Erik Agrell
In optical fiber communication, due to the random variation of the environment, the state of polarization (SOP) fluctuates randomly with time leading to distortion and performance…
Velocity-aware Antenna Selection in Predictor Antenna Systems
Hao Guo, Behrooz Makki, Tommy Svensson
Moving relay (MR), which is a candidate solution for supporting in-vehicle users, has been investigated in different studies. Due to the mobile nature of the MR, acquiring channel…
Low-complexity Voronoi shaping for the Gaussian channel
S. Li, A. Mirani, M. Karlsson +1
Voronoi constellations (VCs) are finite sets of vectors of a coding lattice enclosed by the translated Voronoi region of a shaping lattice, which is a sublattice of the coding latt…
Hierarchical sparse recovery from hierarchically structured measurements with application to massive random access
Benedikt Groß, Axel Flinth, Ingo Roth +2
A new family of operators, coined hierarchical measurement operators, is introduced and discussed within the well-known hierarchical sparse recovery framework. Such operator is a c…
On Doped SC-LDPC Codes for Streaming
Roman Sokolovskii, Alexandre Graell i Amat, Fredrik Brännström
In streaming applications, doping improves the performance of spatially-coupled low-density parity-check (SC-LDPC) codes by creating reduced-degree check nodes in the coupled chain…
Discrete-time models and performance of phase noise channels
Amina Piemontese, Giulio Colavolpe, Thomas Eriksson
This paper deals with the phase noise affecting communication systems, where local oscillators are employed to obtain reference signals for carrier and timing synchronizations. The…
Performance Prediction Recipes for Optical Links
Erik Agrell, Marco Secondini, Alex Alvarado +1
Although forward error-correction (FEC) coding is an essential part of modern fiber-optic communication systems, it is impractical to implement and evaluate FEC in transmission exp…
Compressed Shaping: Concept and FPGA Demonstration
Tsuyoshi Yoshida, Koji Igarashi, Magnus Karlsson +1
Probabilistic shaping (PS) has been widely studied and applied to optical fiber communications. The encoder of PS expends the number of bit slots and controls the probability distr…
