Summary:[...]the complexity remains high because each iteration may include singular value decomposition, the matrix inversion, and so on that motivates us to split the hybrid precoding and combining problem into sub-problems. To enable multi-gigabit data rates, the integration of mm Wave bands with multi-user Massive MIMO (MU-Massive MIMO) systems are a vital aspect [8]. [...]the large-scale antenna arrays for each Base Station (BS) and Mobile Station (MSs), as well as the precoding (beamforming), which contribute to the elimination of user's interference and achieve various benefits such as canceling out noise and fast fading through highly directional beamforming [9, 10]. [...]the authors in [37] suggested an iterative algorithm using the KKT-based penalty dual decomposition technique. [...]a convex optimization problem is applied and solved to estimate the digital precoding, which is used to eliminate inter-user interference.
