The Application of MIMO to Non-Orthogonal Multiple Access [PDF]
IEEE Transactions on Wireless Communications, 2015 This paper considers the application of multiple-input multiple-output (MIMO) techniques to nonorthogonal multiple access (NOMA) systems. A new design of precoding and detection matrices for MIMO-NOMA is proposed and its performance is analyzed for the ...
