Spectral Temporal Graph Neural Network for massive MIMO CSI Prediction
Sharan Mourya, Pavan Reddy, SaiDhiraj Amuru +1
In the realm of 5G communication systems, the accuracy of Channel State Information (CSI) prediction is vital for optimizing performance. This letter introduces a pioneering approa…
On the Coverage of Cognitive mmWave Networks with Directional Sensing and Communication
Shuchi Tripathi, Abhishek K. Gupta, SaiDhiraj Amuru
Millimeter-waves' propagation characteristics create prospects for spatial and temporal spectrum sharing in a variety of contexts, including cognitive spectrum sharing (CSS). Howev…
Multi-Task Learning for Multi-User CSI Feedback
Sharan Mourya, SaiDhiraj Amuru, Kiran Kumar Kuchi
Deep learning-based massive MIMO CSI feedback has received a lot of attention in recent years. Now, there exists a plethora of CSI feedback models mostly based on auto-encoders (AE…
Optimizing the Placement and Beamforming of RIS in Cellular Networks: A System-Level Modeling Perspective
Pavan Reddy M., SaiDhiraj Amuru, Kiran Kuchi
In this letter, we present in detail the system-level modeling of reconfigurable intelligent surface (RIS)-assisted cellular systems by considering a 3-dimensional channel model be…
6G White Paper on Machine Learning in Wireless Communication Networks
Samad Ali, Walid Saad, Nandana Rajatheva +24
The focus of this white paper is on machine learning (ML) in wireless communications. 6G wireless communication networks will be the backbone of the digital transformation of socie…
On the Phase Tracking Reference Signal (PT-RS) Design for 5G New Radio (NR)
Yinan Qi, Mythri Hunukumbure, Hyungju Nam +2
The volume of mobile data traffic has been driven to an unprecedented high level due to the proliferation of smartphones/mobile devices that support a wide range of broadband appli…
On Jamming Against Wireless Networks
SaiDhiraj Amuru, Harpreet S. Dhillon, R. Michael Buehrer
In this paper, we study jamming attacks against wireless networks. Specifically, we consider a network of base stations (BS) or access points (AP) and investigate the impact of a f…
Jamming Bandits
SaiDhiraj Amuru, Cem Tekin, Mihaela van der Schaar +1
Can an intelligent jammer learn and adapt to unknown environments in an electronic warfare-type scenario? In this paper, we answer this question in the positive, by developing a co…
On the Degrees-of-freedom of the 3-user MISO Broadcast Channel with Hybrid CSIT
SaiDhiraj Amuru, Ravi Tandon, Shlomo Shamai
The 3-user multiple-input single-output (MISO) broadcast channel (BC) with hybrid channel state information at the transmitter (CSIT) is considered. In this framework, there is per…
Towards Optimal Secure Distributed Storage Systems with Exact Repair
Ravi Tandon, SaiDhiraj Amuru, T. Charles Clancy +1
Distributed storage systems in the presence of a wiretapper are considered. A distributed storage system (DSS) is parameterized by three parameters (n, k,d), in which a file stored…
Retroactive Anti-Jamming for MISO Broadcast Channels
SaiDhiraj Amuru, Ravi Tandon, R. Michael Buehrer +1
Jamming attacks can significantly impact the performance of wireless communication systems. In addition to reducing the capacity, such attacks may lead to insurmountable overhead i…
