In NOMA achieving fairness in data transmission for all users is one of the key challenges. It implies a fair allocation of resources among users according to a given criterion. NOMA systems are based on the discreteness of the data source, since the

In the paper, we proposed a method of space-time diversity on the transmitting side, combining a closed feedback and quasi-orthogonal space-time coding technique called closed-loop control with quasi-orthogonal space-time block coding (QO-STBC). For
