In an effort to have further gains over the initial works, which build upon the assumption of time division multiple access, the combined use of orthogonal frequency division multiplexing (OFDM) with NCC has been proposed in the literature. In this paper, we consider orthogonal frequency division multiple access (OFDMA), an extension of the OFDM to a multiuser system where subsets of carriers are assigned to different users. We derive a closed-form expression for the outage probability of the system under consideration and present the diversity-multiplexing tradeoff (DMT) analysis. Our results demonstrate that NCC-OFDMA system is able to fully exploit both frequency and spatial diversity. Simulation results are presented to verify our theoretical analysis.engrestrictedAccessconferenceObject4368437300037170810409710.1109/ICC.2015.7249010Network coded cooperation (NCC)Orthogonal frequencyDivision multiple access (OFDMA)Diversity-multiplexing tradeoff (DMT)2-s2.0-84953731314
