On the Adversarial Vulnerability of Neural Receivers with Unrolled LDPC Decoders
Aakash Saini, Jafar Aco Mohammadi, Wolfgang Gerstacker
Neural receivers for 5G New Radio (NR) match classical model-based receivers in link-level performance, but their robustness to adversarial perturbations at the receiver input rema…
Constellation Shaping under Phase Noise Impairment for Sub-THz Communications
Dileepa Marasinghe, Le Hang Nguyen, Jafar Mohammadi +3
The large untapped spectrum in the sub-THz allows for ultra-high throughput communication to realize many seemingly impossible applications in 6G. One of the challenges in radio co…
Blind Coherent Preamble Detection via Neural Networks
Jafar Mohammadi, Gerhard Schreiber, Thorsten Wild +1
In wireless communications systems, the user equipment (UE) transmits a random access preamble sequence to the base station (BS) to be detected and synchronized. In standardized ce…
Strong Secrecy and Stealth for Broadcast Channels with Confidential Messages
Igor Bjelakovic, Jafar Mohammadi, Sławomir Stańczak
We consider a discrete memoryless broadcast channel consists of two users and a sender. The sender has two independent confidential messages for each user. We extend the work of Li…
A Simple Algorithm for Approximation by Nomographic Functions
Steffen Limmer, Jafar Mohammadi, Slawomir Stanczak
This paper introduces a novel algorithmic solution for the approximation of a given multivariate function by a nomographic function that is composed of a one-dimensional continuous…
