Rethinking Secure Precoding via Interference Exploitation: A Smart Eavesdropper Perspective
Qian Xu, Pinyi Ren, A. Lee Swindlehurst
Based on the concept of constructive interference (CI), multiuser interference (MUI) has recently been shown to be beneficial for communication secrecy. A few CI-based secure preco…
Code-Frequency Block Group Coding for Anti-Spoofing Pilot Authentication in Multi-Antenna OFDM Systems
Dongyang Xu, Pinyi Ren, James A. Ritcey +1
A pilot spoofer can paralyze the channel estimation in multi-user orthogonal frequency-division multiplexing (OFD- M) systems by using the same publicly-known pilot tones as legiti…
Optimal Relay Power Allocation for Amplify-and-Forward Relay Networks with Non-linear Power Amplifiers
Chao Zhang, Pinyi Ren, Jingbo Peng +3
In this paper, we propose an optimal relay power allocation of an Amplify-and-Forward relay networks with non-linear power amplifiers. Based on Bussgang Linearization Theory, we de…
A Multi-Channel Diversity Based MAC Protocol for Power-Constrained Cognitive Ad Hoc Networks
Yichen Wang, Pinyi Ren, Qinghe Du +1
One of the major challenges in the medium access control (MAC) protocol design over cognitive Ad Hoc networks (CAHNs) is how to efficiently utilize multiple opportunistic channels,…
Statistical Delay Control and QoS-Driven Power Allocation Over Two-Hop Wireless Relay Links
Qinghe Du, Yi Huang, Pinyi Ren +1
The time-varying feature of wireless channels usually makes the hard delay bound for data transmissions unrealistic to guarantee. In contrast, the statistically-bounded delay with…
The Effects of Narrowband Interference on Finite-Resolution IR-UWB Digital Receiver
chao zhang, Huarui Yin, Pinyi Ren
Finite-resolution digital receiver is recently considered as a potential way to Ultra Wide Band (UWB) communication systems due to its ability of mitigating the challenge of Analog…
