On the Capacity of Correlated Phase-Noise Channels: An Electro-Optic Frequency Comb Example
Mohammad Farsi, Hamdi Joudeh, Gabriele Liga +3
The capacity of a discrete-time channel with correlated phase noises is investigated. In particular, the electro-optic frequency comb system is considered, where the phase noise of…
Coded Modulation Schemes for Voronoi Constellations
S. Li, A. Mirani, M. Karlsson +1
Multidimensional Voronoi constellations (VCs) are shown to be more power-efficient than quadrature amplitude modulation (QAM) formats given the same uncoded bit error rate, and als…
The Voronoi Region of the Barnes-Wall Lattice
Daniel Pook-Kolb, Erik Agrell, Bruce Allen
We give a detailed description of the Voronoi region of the Barnes-Wall lattice , including its vertices, relevant vectors, and symmetry group. The exact value of its quant…
Exact calculation of quantizer constants for arbitrary lattices
Daniel Pook-Kolb, Bruce Allen, Erik Agrell
We present an algorithm for the exact computer-aided construction of the Voronoi cells of lattices with known symmetry group. Our algorithm scales better than linearly with the tot…
Data-Driven Estimation of Capacity Upper Bounds
Christian Häger, Erik Agrell
We consider the problem of estimating an upper bound on the capacity of a memoryless channel with unknown channel law and continuous output alphabet. A novel data-driven algorithm…
Benchmarking and Interpreting End-to-end Learning of MIMO and Multi-User Communication
Jinxiang Song, Christian Häger, Jochen Schröder +3
End-to-end autoencoder (AE) learning has the potential of exceeding the performance of human-engineered transceivers and encoding schemes, without a priori knowledge of communicati…
