Data-Driven Subsampling in the Presence of an Adversarial Actor

no code implementations7 Jan 2024 Abu Shafin Mohammad Mahdee Jameel, Ahmed P. Mohamed, Jinho Yi, Aly El Gamal, Akshay Malhotra

In this paper, we investigate the effects of an adversarial attack on an AMC system that employs deep learning models both for AMC and for subsampling.

Deep OFDM Channel Estimation: Capturing Frequency Recurrence

no code implementations7 Jan 2024 Abu Shafin Mohammad Mahdee Jameel, Akshay Malhotra, Aly El Gamal, Shahab Hamidi-Rad

In this paper, we propose a deep-learning-based channel estimation scheme in an orthogonal frequency division multiplexing (OFDM) system.

Unsupervised Learning for Pilot-free Transmission in 3GPP MIMO Systems

no code implementations4 Feb 2023 Omar M. Sleem, Mohamed Salah Ibrahim, Akshay Malhotra, Mihaela Beluri, Philip Pietraski

This paper introduces a new downlink data structure that is free from demodulation reference signals (DM-RS), and hence does not require any channel estimation at the receiver.
