Wireless Information and Power Transfer: A Dynamic Power Splitting Approach
Liang Liu, Rui Zhang, Kee-Chaing Chua
Scavenging energy from ambient radio signals, namely wireless energy harvesting (WEH), has recently drawn significant attention. In this paper, we consider a point-to-point wireles…
Wireless Information Transfer with Opportunistic Energy Harvesting
Liang Liu, Rui Zhang, Kee-Chaing Chua
Energy harvesting is a promising solution to prolong the operation of energy-constrained wireless networks. In particular, scavenging energy from ambient radio signals, namely wire…
Achieving Global Optimality for Weighted Sum-Rate Maximization in the K-User Gaussian Interference Channel with Multiple Antennas
Liang Liu, Rui Zhang, Kee-Chaing Chua
Characterizing the global maximum of weighted sum-rate (WSR) for the K-user Gaussian interference channel (GIC), with the interference treated as Gaussian noise, is a key problem i…
