Abstract
This paper considers a bistatic backscatter communication network (BCN) designed with multiple antennas and nonorthogonal multiple access (NOMA) to provide massive connectivity for sustainable Internet of Things. As a way of leveraging the maximum fairness among the devices, we optimize the transmit beamforming at a carrier source, receive beamforming at a data collector, and reflection coefficients at backscatter devices. The results show that the bistatic BCN can outperform the monostatic counterpart by deploying the source near to the devices.
