Abstract(in English) | In 5th generation mobile communication system (5G) and beyond, non-orthogonal multiple access (NOMA) has been studied to improves spectrum efficiency since multiple signals are superposed. Although power domain NOMA is a promising candidate, it is vulnerable to the nonlinearity of transceiver circuit. In order to reduce the influence of nonlinear distortion, a blind nonlinear compensation (BNLC) scheme in the receiver side of downlink NOMA system has been studied. However, it is not trivial how to mitigate effect of the channel frequency selectivity so as to compensate the transceiver nonlinearity via BNLC. In this paper, we propose a hybrid scheme consisting of BNLC and frequency domain equalizer (FDE) in the downlink power domain NOMA system and clarify its effectiveness by computer simulations. |
