Abstract

In this paper, we investigate the effects of interference among the cell edge users under cooperative non-orthogonal multiple access (NOMA) system. The base stations (BSs) cooperative with each other for downlink transmission. The information rate of cell-edge users (CEU) are derived for two system models: first model with inter-user (i.e., Users on the same cell edge) interference only and second model which has inter-user and intra-cell interference. The achievable information rate of both the systems which employs different cancellation techniques at the transmitter and receiver side are compared with the conventional system were no interference cancellation techniques are used. The simulation results shows that the proposed system performs better than the conventional system, even under low signal-to-noise ratio (SNR) value.
