Zero-forcing approach is applied efficiently to precode/detect signals in both UL and DL. To achieve the SE maximization, we formulate an optimized problem where the transmit power of Base station (BS) and users are jointly considered. Numerical results are used to show that the proposed algorithm may bring significant SE gain over the previous approaches under realistic channel conditions. %U http://ict.jst.udn.vn/index.php/jst/article/view/120 %J Journal of Science and Technology: Issue on Information and Communications Technology %0 Journal Article %R 10.31130/ict-ud.2020.120 %P 43-48%V 18 %N 12.2 %@ 1859-1531 %8 2020-12-29
