Capacity improvement of non-orthogonal multiple access downlink transmission by orbital angular momentum based mode division multiple access

In this paper, non-orthogonal multiple access (NOMA) downlink transmission is integrated with orbital angular momentum (OAM) based mode division multiple access (MDMA), called NOMA-OAM-MDMA. Different OAM modes can generate different OAM waves for different superimposed signals. So, every OAM wave will be transmitted a superimposed signal from the base station to the cell center user (CCU) and cell edge user (CEU). In this way, multiple OAM waves with multiple superimposed signals will transmit from BS to CCU and CEU simultaneously to enhance the capacity of NOMA downlink transmission. Finally, the effectiveness of the proposed schemes over the existing scheme and conventional orthogonal multiple access based scheme are demonstrated through the result analysis.
