Analyzing α-divergence in Gaussian Rate-Distortion-Perception Theory
Martha V. Sourla, Giuseppe Serra, Photios A. Stavrou +1
The problem of estimating the information rate distortion perception function (RDPF), which is a relevant information-theoretic quantity in goal-oriented lossy compression and sema…
Inference-Based Resource Allocation for Multi-Cell Backscatter Sensor Networks
Panos N. Alevizos, Aggelos Bletsas
This work studies inference-based resource allocation in ultra low-power, large-scale backscatter sensor networks (BSNs). Several ultra-low cost and power sensor devices (tags) are…
Low-Complexity Multiuser QAM Detection for Uplink 1-bit Massive MIMO
Panos Alevizos
This work studies multiuser detection for one-bit massive multiple-input multiple-output (MIMO) systems in order to diminish the power consumption at the base station (BS). A low-c…
Limited Feedback Channel Estimation in Massive MIMO with Non-uniform Directional Dictionaries
Panos N. Alevizos, Xiao Fu, Nicholas D. Sidiropoulos +2
Channel state information (CSI) at the base station (BS) is crucial to achieve beamforming and multiplexing gains in multiple-input multiple-output (MIMO) systems. State-of-the-art…
Design of LDPC Codes for the Unequal Power Two-User Gaussian Multiple Access Channel
Alexios Balatsoukas Stimming, Athanasios P. Liavas
In this work, we describe an LDPC code design framework for the unequal power two-user Gaussian multiple access channel using EXIT charts. We show that the sum-rate of the LDPC cod…
Sensitive and Nonlinear Far Field RF Energy Harvesting in Wireless Communications
Panos N. Alevizos, Aggelos Bletsas
This work studies both limited sensitivity and nonlinearity of far field RF energy harvesting observed in reality and quantifies their effect, attempting to fill a major hole in th…
