Query: Beamforming with Multiple One-Bit Wireless Transceivers   Classical beamforming techniques rely on highly linear transmitters and
receivers to allow phase-coherent combining at the transmitter and receiver.
The transmitter uses beamforming to steer signal power towards the receiver,
and the receiver uses beamforming to gather and coherently combine the signals
from multiple receiver antennas. When the transmitters and receivers are
instead constrained for power and cost reasons to be non-linear one-bit
devices, the potential advantages and performance metrics associated with
beamforming are not as well understood. We define beamforming at the
transmitter as a codebook design problem to maximize the minimum distance
between codewords. We define beamforming at the receiver as the maximum
likelihood detector of the transmitted codeword. We show that beamforming with
one-bit transceivers is a constellation design problem, and that we can come
within a few dB SNR of the capacity attained by linear transceivers.
