Volume-Based Lower Bounds to the Capacity of the Gaussian Channel Under Pointwise Additive Input Constraints
Neri Merhav, Shlomo Shamai
We present a family of relatively simple and unified lower bounds on the capacity of the Gaussian channel under a set of pointwise additive input constraints. Specifically, the adm…
Achievable Rates for a Distributed Antenna System with No Channel State Information at the Central Processor
Yi Song, Hao Xu, Kai Wan +3
A recent trend in wireless communications considers the migration of traditional monolithic base stations to the so-called disaggregated architecture, where radio units (RUs) imple…
SIM-Enabled Hybrid Digital-Wave Beamforming for Fronthaul-Constrained Cell-Free Massive MIMO Systems
Eunhyuk Park, Seok-Hwan Park, Osvaldo Simeone +2
As the dense deployment of access points (APs) in cell-free massive multiple-input multiple-output (CF-mMIMO) systems presents significant challenges, per-AP coverage can be expand…
An Analytical Study of the Min-Sum Approximation for Polar Codes
Nir Chisnevski, Ido Tal, Shlomo Shamai
The min-sum approximation is widely used in the decoding of polar codes. Although it is a numerical approximation, hardly any penalties are incurred in practice. We give a theoreti…
Broadcast Channel Cooperative Gain: An Operational Interpretation of Partial Information Decomposition
Chao Tian, Shlomo Shamai
Partial information decomposition has recently found applications in biological signal processing and machine learning. Despite its impacts, the decomposition was introduced throug…
On entropy-constrained Gaussian channel capacity via the moment problem
Adway Girish, Shlomo Shamai, Emre Telatar
We study the capacity of the power-constrained additive Gaussian channel with an entropy constraint at the input. In particular, we characterize this capacity in the low signal-to-…
