A Machine Learning Framework for Resource Allocation Assisted by Cloud Computing
Jun-Bo Wang, Junyuan Wang, Yongpeng Wu +4
Conventionally, the resource allocation is formulated as an optimization problem and solved online with instantaneous scenario information. Since most resource allocation problems…
Message-Passing Receiver Design for Joint Channel Estimation and Data Decoding in Uplink Grant-Free SCMA Systems
Fan Wei, Wen Chen, Yongpeng Wu +2
The conventional grant-based network relies on the handshaking between base station and active users to achieve dynamic multi-user scheduling, which may cost large signaling overhe…
GPI-based Secrecy Rate Maximization Beamforming Scheme for Wireless Transmission with AN-aided Directional Modulation
Hai Yu, Simin Wan, Wenlong Cai +7
In a directional modulation network, a general power iterative (GPI) based beamforming scheme is proposed to maximize the secrecy rate (SR), where there are two optimization variab…
2D Unitary ESPRIT Based Super-Resolution Channel Estimation for Millimeter-Wave Massive MIMO with Hybrid Precoding
Anwen Liao, Zhen Gao, Yongpeng Wu +2
Millimeter-wave (mmWave) massive multiple-input multiple-output (MIMO) with hybrid precoding is a promising technique for the future 5G wireless communications. Due to a large numb…
Pilot Optimization and Power Allocation for OFDM-based Full-duplex Relay Networks with IQ-imbalances
Jin Wang, Hai Yu, Yongpeng Wu +4
In OFDM relay networks with IQ imbalances and full-duplex relay station (RS), how to optimize pilot pattern and power allocation using the criterion of minimizing the sum of mean s…
Secure Transmission with Large Numbers of Antennas and Finite Alphabet Inputs
Yongpeng Wu, Jun-Bo Wang, Jue Wang +2
In this paper, we investigate secure transmission over the large-scale multiple-antenna wiretap channel with finite alphabet inputs. First, we investigate the case where instantane…
Outage Performance for Cooperative NOMA Transmission with an AF Relay
Xuesong Liang, Yongpeng Wu, Derrick Wing Kwan Ng +3
This letter studies the outage performance of cooperative non-orthogonal multiple access (NOMA) network with the help of an amplify-and-forward relay. An accurate closed-form appro…
Energy-Efficient Transceiver Design for Hybrid Sub-Array Architecture MIMO Systems
Shiwen He, Chenhao Qi, Yongpen Wu +1
Millimeter-wave (mmWave) communication operated in frequency bands between 30 and 300 GHz has attracted extensive attention due to the potential ability of offering orders of magni…
