An online algorithm for throughput maximization of wireless powered communication networks

Wei-Chiang Li, Hsin-Shan Hsieh, Chong-Yung Chi

ICASSP 2016accepted

Optimizing the system performance of a wireless powered communication network (WPCN) has been extensively studied recently, by incorporating space, frequency and/or time diversity of the channel, etc. However, the time diversity, inherently imposes the causality constraint on the channel state infor…

Energy-efficient precoding matrix design for relay-aided multiuser downlink networks

Wei-Chiang Li, Rui-Yu Chang, Kun-Yu Wang, Chong-Yung Chi

ICASSP 2015accepted

This paper considers the energy-efficient precoding matrix design for relay-aided multiuser downlink multiple-input single-output wireless systems. The precoders of the base station (BS) and the relay station (RS) are designed to maximize the transmit energy efficiency, defined as the ratio between…
