Description
Summary:Due to the lack of spectral resource in traditional low frequency bands and the great demand for capacity of wireless communications, millimeter wave (mmWave) communications is considered as a key technology for the upcoming 5G networks. Large scale antenna arrays and hybrid precoding are employed to compensate the high path loss of the mmWave propagation. In this letter, based on the decomposition of the hybrid precoding problem, we propose a novel algorithm for the mmWave massive multiple-input multiple-output (MIMO) system, which has low computational complexity. In addition, simulations show that the proposed algorithm can achieve near-optimal performance.
