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…

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…

Sum-MSE performance gain of DFT-based channel estimator over frequency-domain LS one in full-duplex OFDM systems with colored interference
Jin Wang, Feng Shu, Jinhui Lu +4
In this paper, we make an investigation on the sum-mean-square-error (sum-MSE) performance gain achieved by DFT-based least-square (LS) channel estimator over frequency-domain LS o…
