Joint Reconfigurable Intelligent Surface Location and Passive Beamforming Optimization for Maximizing the Secrecy-Rate
Haiyan Guo, Zhen Yang, Yulong Zou +3
The physical layer security (PLS) is investigated for reconfigurable intelligent surface (RIS) assisted wireless networks, where a source transmits its confidential information to…
Universal Graph Filter Design based on Butterworth, Chebyshev and Elliptic Functions
Zirui Ge, Haiyan Guo, Tingting Wang +1
Graph filters are crucial tools in processing the spectrum of graph signals. In this paper, we propose to design universal IIR graph filters with low computational complexity by us…
Optimal Fractional Fourier Filtering in Time-vertex Graphs signal processing
Zirui Ge, Haiyan Guo, Tingting Wang +1
Graph signal processing (GSP) is an effective tool in dealing with data residing in irregular domains. In GSP, the optimal graph filter is one of the essential techniques, owing to…
An Iterative Graph Spectral Subtraction Method for Speech Enhancement
Xue Yan, Zhen Yang, Tingting Wang +1
In this paper, we investigate the application of graph signal processing (GSP) theory in speech enhancement. We first propose a set of shift operators to construct graph speech sig…
Security-Reliability Tradeoff for Distributed Antenna Systems in Heterogeneous Cellular Networks
Yulong Zou, Ming Sun, Jia Zhu +1
In this paper, we investigate physical-layer security for a spectrum-sharing heterogeneous cellular network comprised of a macro cell and a small cell, where a passive eavesdropper…
