Abstract: This treatise investigates multistream hybrid beamforming (HBF) for a millimeterwave non-orthogonal multiple access (NOMA) system deployed in a downlink of an urban microcell environment. Maximization problem is developed to optimize sum-rate. For the sake of ensuring high correlation of users' channels, user's clustering and ordering are based on the angle of arrivals and users' channel-weights, respectively. An optimized analog combiner of each user is obtained from the first N s column vectors of the left u… Show more
