The hybrid precoding problem in point-to-point millimeter wave (mmWave) multiple input multiple output (MIMO) for narrowband channel has been established as a Frobenius norm minimization problem. It is translated into trace minimization problem. and two algorithms are proposed to solve it. In the first method based on alternating minimization. https://www.ngetikin.com/mega-save-NHL-Calgary-Flames-Home-Jersey-iPhone-XR-Skin-p120897-hot-value/
