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…
List Decoding and New Bicycle Code Constructions for Quantum LDPC Codes
Sheida Rabeti, Hessam Mahdavifar
In this paper, we propose a new decoder, called the Multiple-Bases Belief-Propagation List Decoder (MBBP-LD), for Quantum Low-Density Parity-Check (QLDPC) codes. It extends the Mul…
Layered Normalized Min-Sum Decoding with Bit Flipping for FDPC Codes
Niloufar Hosseinzadeh, Mohsen Moradi, Hessam Mahdavifar
Fair-density parity-check (FDPC) codes have been recently introduced demonstrating improved performance compared to low-density parity-check (LDPC) codes standardized in 5G systems…
Efficient Low-Memory Fast Stack Decoding with Variance Polarization for PAC Codes
Mohsen Moradi, Hessam Mahdavifar
Polarization-adjusted convolutional (PAC) codes have recently emerged as a promising class of error-correcting codes, achieving near-capacity performance particularly in the short…
A Locally Differential Private Coding-Assisted Succinct Histogram Protocol
Hsuan-Po Liu, Hessam Mahdavifar
A succinct histogram captures frequent items and their frequencies across clients and has become increasingly important for large-scale, privacy-sensitive machine learning applicat…
On the High-Rate FDPC Codes: Construction, Encoding, and a Generalization
Mohsen Moradi, Sheida Rabeti, Hessam Mahdavifar
Recently introduced Fair-Density Parity-Check (FDPC) codes, targeting high-rate applications, offer superior error-correction performance (ECP) compared to 5G Low-Density Parity-Ch…
Bounds and New Constructions for Girth-Constrained Regular Bipartite Graphs
Sheida Rabeti, Mohsen Moradi, Hessam Mahdavifar
In this paper, we explore the design and analysis of regular bipartite graphs motivated by their application in low-density parity-check (LDPC) codes specifically with constrained…
Efficient Covering Using Reed--Solomon Codes
Samin Riasat, Hessam Mahdavifar
We propose an efficient algorithm to find a Reed-Solomon (RS) codeword at a distance within the covering radius of the code from any point in its ambient Hamming space. To the best…
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…
