Selective mapping (SLM) and partial transmit sequence (PTS) are attractive schemes for
mitigating the high peak power inherent in orthogonal frequency division multiplexing …

Cognitive radio is more than just radio environment awareness, and more importantly, has
the ability to interact with the environment in the best way possible. Ideally, cognitive radios …

In this paper, we present a cross-layer perspective on data transmission in energy
harvesting cognitive radio networks. The physical layer power allocation and network layer …

Dynamic frequency allocation (DFA) with massive multiple-input multiple-output (MIMO) is a
promising candidate for multicell communications where massive MIMO is adopted to …

In this paper, a call admission control algorithm based on inter-network cooperation is
proposed via a Stackelberg game framework for cognitive heterogeneous networks. The call …

In consideration of an orthogonal-frequency-division-multiplexing access cognitive two-way
relay network with imperfect spectrum sensing, we propose a joint resource allocation …

In this paper, we investigate the robust power allocation issue in orthogonal frequency
division multiplexing-based cognitive radio networks (CRNs) with unavoidable uncertainties …

Multiuser transmission with shared spectrum is investigated in the presence of energy
harvesting. For each user, the data generation, the harvested energy arrival, and the …

This work investigates power allocation algorithms for capacity maximization of a non-
contiguous orthogonal frequency division multiplexing (NC-OFDM) based cognitive radio …

摘要能量效率(EE, energy efficiency) 和频谱效率(SE, spectral efficiency)
是无线移动通信系统中两个重要的性能度量. 在过去几十年中, 工业界和学术界开展了大量的 …
