Optimal Power Allocation for Outage Minimization in Fading Channels with Energy Harvesting Constraints
Chuan Huang, Rui Zhang, Shuguang Cui
This paper studies the optimal power allocation for outage minimization in point-to-point fading channels with the energy-harvesting constraints and channel distribution informatio…
Optimal Power and Range Adaptation for Green Broadcasting
Shixin Luo, Rui Zhang, Teng Joon Lim
Improving energy efficiency is key to network providers maintaining profit levels and an acceptable carbon footprint in the face of rapidly increasing data traffic in cellular netw…
Exploiting Network Cooperation in Green Wireless Communication
Yulong Zou, Jia Zhu, Rui Zhang
There is a growing interest in energy efficient or so-called "green" wireless communication to reduce the energy consumption in cellular networks. Since today's wireless terminals…
Cognitive Energy Harvesting and Transmission from a Network Perspective
Seunghyun Lee, Kaibin Huang, Rui Zhang
Wireless networks can be self-sustaining by harvesting energy from radio-frequency (RF) signals. Building on classic cognitive radio networks, we propose a novel method for network…
Improving Achievable Rate for the Two-User SISO Interference Channel with Improper Gaussian Signaling
Yong Zeng, Cenk M. Yetis, Erry Gunawan +2
This paper studies the achievable rate region of the two-user single-input-single-output (SISO) Gaussian interference channel, when the improper Gaussian signaling is applied. Unde…
Multi-Cell Random Beamforming: Achievable Rate and Degrees of Freedom Region
Hieu Duy Nguyen, Rui Zhang, Hon Tat Hui
Random beamforming (RBF) is a practically favourable transmission scheme for multiuser multi-antenna downlink systems since it requires only partial channel state information (CSI)…
