Analog Beamformer Design for Interference Exploitation Based Hybrid Beamforming [PDF]
2018 IEEE 10th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2018 Hybrid analog-digital beamforming has been shown to reduce hardware cost and power consumption in massive MIMO systems, at the expense of increased radiated power for given performance targets. To alleviate the above shortfall, in this paper we exploit the concept of constructive interference (CI) that has been shown to offer significant radiated power
