Distributed transmit beamforming: Phase convergence improvement using enhanced one-bit feedback

Tushar, Wayes; Smith, David; Zhang, Andrew; Lamahewa, Tharaka A; Abhayapala, Thushara


Transmission of signals using multiple antennas can significantly improve the energy efficiency of a wireless network, and the proper alignment of the transmitted signals' phases at the receiver is one of the key factors so this efficiency improvement can be realized. In a time-varying channel, due to the relative motion between the transmitters and the receiver, the development of a scheme that guarantees such alignment is very challenging. In this paper, considering a distributed transmit...[Show more]
