MMSE Channel Estimation for Two-Port Demodulation Reference Signals in New Radio
Dejin Kong, Xiang-Gen Xia, Pei Liu +1
Two-port demodulation reference signals (DMRS) have been employed in new radio (NR) recently. In this paper, we firstly propose a minimum mean square error (MMSE) scheme with full…
Self-Interference Channel Characterization in Underwater Acoustic In-Band Full-Duplex Communications Using OFDM
Mohammad Towliat, Zheng Guo, Leonard J. Cimini +2
Due to the limited available bandwidth and dynamic channel, data rates are extremely limited in underwater acoustic (UWA) communications. Addressing this concern, in-band fullduple…
On BT-limited Signals
Xiang-Gen Xia
In this paper, we introduce and characterize a subspace of bandlimited signals. The subspace consists of all bandlimited signals such that the non-zero parts of their Fourier t…
Millimeter-Wave Full-Duplex UAV Relay: Joint Positioning, Beamforming, and Power Control
Lipeng Zhu, Jun Zhang, Zhenyu Xiao +3
In this paper, a full-duplex unmanned aerial vehicle (FD-UAV) relay is employed to increase the communication capacity of millimeter-wave (mmWave) networks. Large antenna arrays ar…
