Spectrum and energy efficient solutions for OFDMA collaborative wireless networks
Chang, Zheng (University of Jyväskylä, 2013) -
Energy Efficient Scheduling in Content Distribution Collaborative Mobile Clusters
Hu, Yun; Chen, Yanhui; Chang, Zheng (IEEE, 2020)Most of the existing literatures on green communications aimed to improve the energy efficiency at the base station or data server. However, in order to fully experience high rate broadband multimedia services, prolonging ... -
Energy efficient and distributed resource allocation for wireless powered OFDMA multi-cell networks
Chang, Zheng; Wang, Zhongyu; Guo, Xijuan; Han, Zhu; Ristaniemi, Tapani (IEEE, 2017)In this paper, we investigate the energy efficient resource allocation problem for the wireless powered OFDMA multi-cell networks. In the considered system, the users who have data to transmit in the uplink can only be ... -
Distributed Resource Allocation for Energy Efficiency in OFDMA Multicell Networks with Wireless Power Transfer
Chang, Zheng; Wang, Zhongyu; Guo, Xijuan; Yang, Chungang; Han, Zhu; Ristaniemi, Tapani (Institute of Electrical and Electronics Engineers, 2019)In this paper, an energy-efficient resource allocation problem is investigated for the wireless power transfer (WPT)-enabled OFDMA multicell networks. In the considered system, multiple base stations (BSs) with a large ... -
Energy-Efficient Resource Optimization with Wireless Power Transfer for Secure NOMA Systems
Lei, Lei; Chang, Zheng; Hu, Yun; Ristaniemi, Tapani; Yuan, Yaxiong; Chatzinotas, Symeon (IEEE, 2019)In this paper, we investigate resource allocation algorithm design for secure non-orthogonal multiple access (NOMA) systems empowered by wireless power transfer. With the consideration of an existing eavesdropper, the ...
