Optical Implementation of Butler Matrix for Hardware-Efficient Multiuser Beamforming

Phased antenna arrays have been used extensively for massive MIMO-based multiuser beamforming to improve both the throughput and power efficiency of wireless communication systems. Beamforming can be realized by the Butler matrix, which has been demonstrated in the electric domain. With wireless sys...
