Since cognitive radio (CR) in conjunction with nonorthogonal multiple access is a candidate techniques for future mobile radio networks, realizing underlay spectrum sharing with high capacity gain is an important issue. In this paper, we propose an adaptive linear precoder design for a CR based multiuser MIMO broadcasting system. The proposed adaptive precoder employs regularized channel inversion based on the minimum mean square error criterion (MMSE). Unlike the conventional MMSE based… CONTINUE READING
