title = "Analog Beamforming mm-Wave Two User Non-Orthogonal Multiple Access",
abstract = "In this paper, the authors aim to design analog beam forming weight vector for two user down link non-orthogonal multiple access (NOMA) scenario. Millimeter wave (mm-wave) channel with one line-of-sight (LOS) path and multiple non line-of-sight (NLOS) paths is considered. The components of beamforming vector vary only in phase whereas their magnitudes are same. This restriction guarantees that power amplifiers need not be designed with different power amplification factors, thereby minimizing the complexity of power amplifier design. In this work, two users located at different angle of departure (AoD) with different gains are considered. The weight vector is designed aiming to minimize the total power requirement. Simulation results show that the proposed approach requires less power with minimum complexity compared with the time division multiple access (TDMA) for the same spectral efficiency requirements.",
