Semantic-Aware Neural Video Codec for Error-Resilient Low-Latency Transmission
Matin Mortaheb, Homa Esfahanizadeh, Jinfeng Du +1
Emerging physical AI systems require low-latency, task-oriented video communication over unreliable channels. We propose a semantic-aware multi-level neural video coding method for…
UniTAC: Universal Task-Aware Compression via Weighted Distortion Measures
Homa Esfahanizadeh, Matin Mortaheb, Jinfeng Du +2
Lossy compression is conventionally driven by a task-agnostic distortion (e.g., MSE or MS-SSIM), yet in many emerging applications the receiver cares not about uniform fidelity but…
Towards Robust Semantic Video Transmission over Block Erasure Channels
Nargis Fayaz, Homa Esfahanizadeh, Matin Mortaheb +2
This paper investigates semantic-aware neural joint source-channel coding (JSCC) for robust video transmission over block erasure channels. We propose a neural video compression fr…
Lossy Joint Source-Channel Coding over Unknown Channels
Adeel Mahmood, Harish Viswanathan, Jinfeng Du
We analyze the performance of joint source-channel codes in an unknown-channel framework, where the true channel is unknown but the source distribution is known. We derive achievab…
Block Erasure-Aware Semantic Multimedia Compression via JSCC Autoencoder
Homa Esfahanizadeh, Nargis Fayaz, Jinfeng Du +1
We present an AI-based framework for semantic transmission of multimedia data over band-limited, time-varying channels. The method targets scenarios where large content is split in…
Self-Nomination: Deep Learning for Decentralized CSI Feedback Reduction in MU-MIMO Systems
Juseong Park, Foad Sohrabi, Jinfeng Du +1
This paper introduces a novel deep learning-based user-side feedback reduction framework, termed self-nomination. The goal of self-nomination is to reduce the number of users (UEs)…
Beamforming with hybrid reconfigurable parasitic antenna arrays
Nitish Vikas Deshpande, Miguel Rodrigo Castellanos, Saeed R. Khosravirad +3
A parasitic reconfigurable antenna array is a low-power approach for beamforming using passive tunable elements. Prior work on reconfigurable antennas in communication theory is ba…
Energy-Efficient Flat Precoding for MIMO Systems
Foad Sohrabi, Carl Nuzman, Jinfeng Du +2
This paper addresses the suboptimal energy efficiency of conventional digital precoding schemes in multiple-input multiple-output (MIMO) systems. Through an analysis of the power a…
Analyzing the Scalability of Bi-static Backscatter Networks for Large Scale Applications
Kartik Patel, Junbo Zhang, John Kimionis +3
Backscatter radio is a promising technology for low-cost and low-power Internet-of-Things (IoT) networks. The conventional monostatic backscatter radio is constrained by its limite…
Multi-level Reliability Interface for Semantic Communications over Wireless Networks
Tze-Yang Tung, Homa Esfahanizadeh, Jinfeng Du +1
Semantic communication, when examined through the lens of joint source-channel coding (JSCC), maps source messages directly into channel input symbols, where the measure of success…
A generalization of the achievable rate of a MISO system using Bode-Fano wideband matching theory
Nitish Deshpande, Miguel R. Castellanos, Saeed R. Khosravirad +3
Impedance-matching networks affect power transfer from the radio frequency (RF) chains to the antennas. Their design impacts the signal to noise ratio (SNR) and the achievable rate…
Trade-Off Between Beamforming and Macro-Diversity Gains in Distributed mMIMO
Eduardo Noboro Tominaga, Hsuan-Jung Su, Jinfeng Du +3
Industry and academia have been working towards the evolution from Centralized massive Multiple-Input Multiple-Output (CmMIMO) to Distributed mMIMO (DmMIMO) architectures. Instead…
