Upper and Lower Bounds on the Capacity of Amplitude-Constrained MIMO Channels
Alex Dytso, Mario Goldenbaum, Shlomo Shamai +1
In this work, novel upper and lower bounds for the capacity of channels with arbitrary constraints on the support of the channel input symbols are derived. As an immediate practica…
Comment on the Equality Condition for the I-MMSE Proof of Entropy Power Inequality
Alex Dytso, Ronit Bustin, H. Vincent Poor +1
The paper establishes the equality condition in the I-MMSE proof of the entropy power inequality (EPI). This is done by establishing an exact expression for the deficit between the…
On the Minimum Mean -th Error in Gaussian Noise Channels and its Applications
Alex Dytso, Ronit Bustin, Daniela Tuninetti +3
The problem of estimating an arbitrary random vector from its observation corrupted by additive white Gaussian noise, where the cost function is taken to be the Minimum Mean -th…
On Communication through a Gaussian Channel with an MMSE Disturbance Constraint
Alex Dytso, Ronit Bustin, Daniela Tuninetti +3
This paper considers a Gaussian channel with one transmitter and two receivers. The goal is to maximize the communication rate at the intended/primary receiver subject to a disturb…
Interference as Noise: Friend or Foe?
Alex Dytso, Daniela Tuninetti, Natasha Devroye
This paper shows that for the two-user Gaussian Interference Channel (G-IC) Treating Interference as Noise without Time Sharing (TINnoTS) achieves the closure of the capacity regio…
