Abstract
With the development of the non-orthogonal multiple access (NOMA) technology, cooperative non-orthogonal multiple access (C-NOMA) has received extensive attentions as an expanded version. This paper considers a full duplex (FD) cooperative NOMA (FD-C-NOMA) system, including one base station (BS), one near user and one far user, where the near user serves as the FD decode-and-forward relay to transmit the signals of the far user. As a common practical implementation problem, the impact of imperfect successive interference cancellation (SIC) is taken into account in system performance analysis. Under the given framework, we derive the closed-form outage probability and the approximate closed-form average rate for the near user and the far user. As analytically expected, simulation results verify that the system performance of the FD-C-NOMA is much better than those of non-cooperative NOMA and half duplex cooperative NOMA (HD-C-NOMA) systems. Finally, Monte Carlo simulation proves the accuracy of our calculation.
