Abstract :
This work presents an energy efficient, low-overhead scheme for cooperative beamforming in ad hoc networks. Collaborating nodes retransmit local signals to faraway destinations, multiplying the received analog waveform by a complex weight chosen (in a distributed fashion) to maximize the received SNR. The improvement in SNR is explicitly derived for a large number of cooperating nodes.
