Channel Estimation for Hybrid Massive MIMO Systems with Adaptive-Resolution ADCs
Yalin Wang, Xihan Chen, Yunlong Cai +2
Achieving high channel estimation accuracy and reducing hardware cost as well as power dissipation constitute substantial challenges in the design of massive multiple-input multipl…
Efficient Resource Allocation for Relay-Assisted Computation Offloading in Mobile Edge Computing
Xihan Chen, Yunlong Cai, Qingjiang Shi +3
In this article, we consider the problem of relay assisted computation offloading (RACO), in which user A aims to share the results of computational tasks with another user B throu…
Performance Analysis of User-centric Virtual Cell Dense Networks over mmWave Channels
Jianfeng Shi, Yinlu Wang, Hao Xu +2
This paper analyzes the ergodic capacity of a user-centric virtual cell (VC) dense network, where multiple access points (APs) form a VC for each user equipment (UE) and transmit d…
Secure MIMO Relaying Network: An Artificial Noise Aided Robust Design Approach
Jiaxin Yang, Qiang Li, Benoit Champagne +2
Owing to the vulnerability of relay-assisted and device-to-device (D2D) communications, improving wireless security from a physical layer signal processing perspective is attractin…
Adaptive Reduced-Rank Minimum Symbol-Error-Rate Receive Processing for Large-Scale Multiple-Antenna Systems
Y. Cai, R. C. de Lamare, B. Qin +2
In this work, we propose a novel adaptive reduced-rank receive processing strategy based on joint preprocessing, decimation and filtering (JPDF) for large-scale multiple-antenna sy…
Joint Transceiver Design Algorithms for Multiuser MISO Relay Systems with Energy Harvesting
Yunlong Cai, Ming-Min Zhao, Qingjiang Shi +2
In this paper, we investigate a multiuser relay system with simultaneous wireless information and power transfer. Assuming that both base station (BS) and relay station (RS) are eq…
Security-Reliability Trade-off Analysis of Multi-Relay Aided Decode-and-Forward Cooperation Systems
Jia Zhu, Yulong Zou, Benoit Champagne +2
We consider a cooperative wireless network comprised of a source, a destination and multiple relays operating in the presence of an eavesdropper, which attempts to tap the source-d…
Robust Transceiver Design for MISO Interference Channel with Energy Harvesting
Ming-Min Zhao, Yunlong Cai, Qingjiang Shi +2
In this paper, we consider multiuser multiple-input single-output (MISO) interference channel where the received signal is divided into two parts for information decoding and energ…
Relay-Selection Improves the Security-Reliability Trade-off in Cognitive Radio Systems
Yulong Zou, Benoit Champagne, Wei-Ping Zhu +1
We consider a cognitive radio (CR) network consisting of a secondary transmitter (ST), a secondary destination (SD) and multiple secondary relays (SRs) in the presence of an eavesd…
