Massive MIMO was recently proposed to achieve the advantage of conventional MIMO but on a greater scale. Massive MIMO can provide a much higher capacity without requiring more wireless spectrum. The need for higher data rate led researchers to consider the Millimeter Wave (mmW) band that offers a much larger unused bandwidth. Because of the higher path loss at mmW frequencies, and the poor scattering nature of the mmW channel (fewer paths exist), a hybrid beamforming technique with large antenna arrays and the Alamouti coding scheme are used in this paper to improve the performance of the single-cell mmW massive MIMO systems. Computer simulations have shown that a gain of 20 dB or more can be achieved using the Alamouti code.
