We consider minimizing average transmit-power with finite-rate feedback
for coherent communications in a wireless sensor network (WSN), where sensors communicate with a fusion center(FC)using adaptive modulation and coding over a wireless fading channel. By viewing
the coherent WSN setup as a distributed space-time multi-input single-output (MISO) system, we develop beamforming and resource
allocation strategies and design optimal quantizers when the sensors only have available quantized (Q-) channel state information at the transmitters (CSIT) through a finite-rate feedback channel. Numeri...
