Advancing IIoT with Over-the-Air Federated Learning: The Role of Iterative Magnitude Pruning

no code implementations21 Mar 2024 Fazal Muhammad Ali Khan, Hatem Abou-zeid, Aryan Kaushik, Syed Ali Hassan

Targeting the notion of compact yet robust DNN models, we propose the integration of iterative magnitude pruning (IMP) of the DNN model being trained in an over-the-air FL (OTA-FL) environment for IIoT.

Reconfigurable Intelligent Surfaces Assisted Communication Under Different CSI Assumptions

no code implementations8 Aug 2023 Bayan Al-Nahhas, Qurrat-UI-Ain Nadeem, Aryan Kaushik, Anas Chaaban

This work studies the net sum-rate performance of a distributed reconfigurable intelligent surfaces (RISs)-assisted multi-user multiple-input-single-output (MISO) downlink communication system under imperfect instantaneous-channel state information (I-CSI) to implement precoding at the base station (BS) and statistical-CSI (S-CSI) to design the RISs phase-shifts.

Millimeter Wave Channel Estimation for Lens based Hybrid MIMO with Low Resolution ADCs

no code implementations15 Nov 2022 Evangelos Vlachos, Aryan Kaushik, Muhammad Z. Shakir

We propose an efficient expectation-maximization (EM)-based mmWave channel estimator for a lens-based hybrid MIMO system with low resolution sampling at the receiver.

Flexible Hybrid Beamforming for Spectrally Efficient 6G Joint Radar-Communications

no code implementations15 Nov 2022 Aryan Kaushik, Evangelos Vlachos, Muhammad Z. Shakir, Wonjae Shin, Rongke Liu

The joint-SE based proposed method optimally selects the number of RF chains with flexible hynrid beamforming design.

Pre-scaling and Codebook Design for Joint Radar and Communication Based on Index Modulation

no code implementations20 Nov 2021 Shengyang Chen, Aryan Kaushik, Christos Masouros

This paper develops an efficient index modulation (IM) approach for the joint radar-communication (JRC) system based on a multi-carrier multiple-input multiple-output (MIMO) radar.

Hardware Efficient Joint Radar-Communications with Hybrid Precoding and RF Chain Optimization

no code implementations16 Apr 2021 Aryan Kaushik, Christos Masouros, Fan Liu

In this paper, we aim to achieve energy efficient design with minimum hardware requirement for hybrid precoding, which enables a large number of antennas with minimal number of RF chains, and sub-arrayed multiple-input multiple-output (MIMO) radar based joint radar-communication (JRC) systems.

Virtual Network Function Placement in Satellite Edge Computing with a Potential Game Approach

no code implementations2 Dec 2020 Xiangqiang Gao, Rongke Liu, Aryan Kaushik

We formulate the VNF placement problem with maximum network payoff as a potential game and analyze the problem by a game-theoretical approach.
