Multi-Tag Collision Recovery in UHF-RFID Using Self-Attention Decoding
Talha Akyildiz, Siva Aditya Gooty, Hessam Mahdavifar +1
Passive ultra high frequency (UHF) radio frequency identification (RFID) enables battery-free tags to communicate with a reader through backscatter. When multiple tags respond in t…
Cost-Aware Neural Early Stopping for Local Constraint OSD Decoders
Talha Akyildiz, Hessam Mahdavifar
Local constraint ordered statistics decoding (LC-OSD) provides strong soft decision performance for short block length linear codes, but its practical cost is dominated by the numb…
Multibeam Phased Arrays with Spherical Gold Spatio-temporal Coding for Fading-Resilient and Delay Robust Beam Isolations
Yuan Ma, Mike Ballou, Kyle Richard +2
Future integrated sensing and communication (ISAC) systems require simultaneous multibeam operation with low-latency hardware and robust isolation under synchronization error and f…
Deep Reinforcement Learning-Aided Strategies for Big Data Offloading in Vehicular Networks
Talha Akyildiz, Hessam Mahdavifar
We consider vehicular networking scenarios where existing vehicle-to-vehicle (V2V) links can be leveraged for an effective uploading of large-size data to the network. In particula…
Deep Learning-Enabled Multi-Tag Detection in Ambient Backscatter Communications
Talha Akyildiz, Hessam Mahdavifar
Ambient backscatter communication (AmBC) enables battery-free connectivity by letting passive tags modulate existing RF signals, but reliable detection of multiple tags is challeng…
Efficient Decoders for Sensing Subspace Code
Siva Aditya Gooty, Hessam Mahdavifar
Sparse antenna array sensing of source/target via direction of arrival (DoA) estimation motivates design of the sensing framework in joint communication and sensing (JCAS) systems…
Precoding Design for Limited-Feedback MIMO Systems via Character-Polynomial Codes
Siva Aditya Gooty, Samin Riasat, Hessam Mahdavifar +1
This paper presents a precoding codebook design for limited-feedback multiple-input multiple-output (MIMO) systems under the equal-gain transmission (EGT) constraint. In particular…
Subspace Coding for Spatial Sensing
Hessam Mahdavifar, Robin Rajamäki, Piya Pal
A subspace code is defined as a collection of subspaces of an ambient vector space, where each information-encoding codeword is a subspace. This paper studies a class of spatial se…
Capacity-achieving Polar-based LDGM Codes with Crowdsourcing Applications
James Chin-Jen Pang, Hessam Mahdavifar, S. Sandeep Pradhan
In this paper we study codes with sparse generator matrices. More specifically, codes with a certain constraint on the weight of all the columns in the generator matrix are conside…
Cell Association via Boundary Detection: A Scalable Approach Based on Data-Driven Random Features
Yinsong Wang, Hessam Mahdavifar, Kamran Entesari +1
The problem of cell association is considered for cellular users present in the field. This has become a challenging problem with the deployment of 5G networks which will share the…
