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…
Secret Key Generation via Pulse-Coupled Synchronization
Hessam Mahdavifar, Najme Ebrahimi
A novel framework for sharing common randomness and generating secret keys in wireless networks is considered. In particular, a network of users equipped with pulse oscillators (PO…
Threshold-Secure Coding with Shared Key
Nasser Aldaghri, Hessam Mahdavifar
Cryptographic protocols are often implemented at upper layers of communication networks, while error-correcting codes are employed at the physical layer. In this paper, we consider…
Analog Subspace Coding: A New Approach to Coding for Non-Coherent Wireless Networks
Mahdi Soleymani, Hessam Mahdavifar
We provide a novel framework to study subspace codes for non-coherent communications in wireless networks. To this end, an analog operator channel is defined with inputs and output…
Covert Millimeter-Wave Communication via a Dual-Beam Transmitter
Mohammad Vahid Jamali, Hessam Mahdavifar
In this paper, we investigate covert communication over millimeter-wave (mmWave) frequencies. In particular, a dual-beam mmWave transmitter, comprised of two independent antenna ar…
Physical Layer Secret Key Generation in Static Environments
Nasser Aldaghri, Hessam Mahdavifar
Two legitimate parties, referred to as Alice and Bob, wish to generate secret keys from the wireless channel in the presence of an eavesdropper, referred to as Eve, in order to use…
Coded Distributed Computing: Performance Limits and Code Designs
Mohammad Vahid Jamali, Mahdi Soleymani, Hessam Mahdavifar
We consider the problem of coded distributed computing where a large linear computational job, such as a matrix multiplication, is divided into smaller tasks, encoded using an…
Coding for Crowdsourced Classification with XOR Queries
James Chin-Jen Pang, Hessam Mahdavifar, S. Sandeep Pradhan
This paper models the crowdsourced labeling/classification problem as a sparsely encoded source coding problem, where each query answer, regarded as a code bit, is the XOR of a sma…
Uplink Non-Orthogonal Multiple Access over Mixed RF-FSO Systems
Mohammad Vahid Jamali, Hessam Mahdavifar
In this paper, we consider a relay-assisted uplink non-orthogonal multiple access (NOMA) system. In this system, two radio frequency (RF) users are grouped for simultaneous transmi…
