Distributed transmit beamforming: Performance improvement using a two-bit feedback scheme

Tushar, Wayes; Smith, David; Saad, Walid; Poor, H. Vincent

Description

In this paper a distributed transmit beamforming technique is proposed for time-varying wireless communication channels that improves the signal gain at the receiving terminal, and thus yielding an enhanced signal-to-interference- plus-noise ratio. In this regard, a two-bit feedback algorithm, with considerable gains in terms of received signal strength (RSS), is proposed for optimizing the phase synchronization of signals beamformed from distributed transmitters towards a moving receiver. It...[Show more]
