Abstract
A successive interference cancellation (SIC) approach for power domain non-orthogonal multiple access (NOMA) offers concurrent multiple users serving within the same resource block. Comparing to orthogonal multiple access (OMA), NOMA helps increasing spectral efficiency, user fairness, and reduce delay. The interference signal that has been decoded from the initial step of the SIC procedure can be combined with relaying via coordinated direct and relay transmission to extend coverage and enhance communication rate of existing NOMA network. Many works have tried to exploit this idea but do not consider the fact that the relay might be selfish due to its energy limitation. In that case, energy incentive from information source might be allocated to the relay to encourage cooperative communication by simultaneous wireless information and power transfer (SWIPT). In NOMA-based wireless-powered communication networks (WPCN), the source can collect the necessary energy incentive from power beacon to send it to a SWIPT relay when it is in the close vicinity of the power beacon. Therefore, this thesis is dedicated to the performance evaluation of power beacon-assisted CDRT in NOMA network with selfish but SWIPT capable relay. We also derive exact and approximated analytical results to compare the outage performance between our approach and a recent work of [1]. Simulation results from figures 2.7 and 2.8 in section 2.4 confirm the validity of our approach and show that we can perform better in terms of interference reduction for the near user by exploiting SIC when compare with the recent work of [1].
