Finite Field Multiple Access
Qi-yue Yu, Jiang-xuan Li, Shu Lin
In the past several decades, various techniques have been developed and used for multiple-access (MA) communications. With the new applications for 6G, it is desirable to find new…
Implicit Regularization for Group Sparsity
Jiangyuan Li, Thanh V. Nguyen, Chinmay Hegde +1
We study the implicit regularization of gradient descent towards structured sparsity via a novel neural reparameterization, which we call a diagonally grouped linear neural network…
Deep Spatio-Temporal Wind Power Forecasting
Jiangyuan Li, Mohammadreza Armandpour
Wind power forecasting has drawn increasing attention among researchers as the consumption of renewable energy grows. In this paper, we develop a deep learning approach based on en…
Implicit Sparse Regularization: The Impact of Depth and Early Stopping
Jiangyuan Li, Thanh V. Nguyen, Chinmay Hegde +1
In this paper, we study the implicit bias of gradient descent for sparse regression. We extend results on regression with quadratic parametrization, which amounts to depth-2 diagon…
Improving Physical Layer Secrecy Using Full-Duplex Jamming Receivers
Gan Zheng, Ioannis Krikidis, Jiangyuan Li +2
This paper studies secrecy rate optimization in a wireless network with a single-antenna source, a multi-antenna destination and a multi-antenna eavesdropper. This is an unfavorabl…
Physical Layer Security with Uncoordinated Helpers Implementing Cooperative Jamming
Shuangyu Luo, Jiangyuan Li, Athina Petropulu
A wireless communication network is considered, consisting of a source (Alice), a destination (Bob) and an eavesdropper (Eve), each equipped with a single antenna. The communicatio…
Outage Constrained Secrecy Rate Maximization Using Cooperative Jamming
Shuangyu Luo, Jiangyuan Li, Athina Petropulu
We consider a Gaussian MISO wiretap channel, where a multi-antenna source communicates with a single-antenna destination in the presence of a single-antenna eavesdropper. The commu…
Explicit Solution of Worst-Case Secrecy Rate for MISO Wiretap Channels with Spherical Uncertainty
Jiangyuan Li, Athina P. Petropulu
A multiple-input single-output (MISO) wiretap channel model is considered, that includes a multi-antenna transmitter, a single-antenna legitimate receiver and a single-antenna eave…
Closed Form Secrecy Capacity of MIMO Wiretap Channels with Two Transmit Antennas
Jiangyuan Li, Athina Petropulu
A Gaussian multiple-input multiple-output (MIMO) wiretap channel model is considered. The input is a two-antenna transmitter, while the outputs are the legitimate receiver and an e…
On Cooperative Beamforming Based on Second-Order Statistics of Channel State Information
Jiangyuan Li, Athina P. Petropulu, H. Vincent Poor
Cooperative beamforming in relay networks is considered, in which a source transmits to its destination with the help of a set of cooperating nodes. The source first transmits loca…

Jiangyuan Li, Athina P. Petropulu
A Gaussian multiple-input single-output (MISO) wiretap channel model is considered, where there exists a transmitter equipped with multiple antennas, a legitimate receiver and an e…
Optimal Cooperative Relaying Schemes for Improving Wireless Physical Layer Security
Jiangyuan Li, Athina P. Petropulu, Steven Weber
We consider a cooperative wireless network in the presence of one of more eavesdroppers, and exploit node cooperation for achieving physical (PHY) layer based security. Two differe…
Transmitter Optimization for Achieving Secrecy Capacity in Gaussian MIMO Wiretap Channels
Jiangyuan Li, Athina Petropulu
We consider a Gaussian multiple-input multiple-output (MIMO) wiretap channel model, where there exists a transmitter, a legitimate receiver and an eavesdropper, each node equipped…
