Abstract Future wireless networks demand high spectral efficiency, energy efficiency
and reliability. Cooperative non-orthogonal multiple access (NOMA) with simultaneous
wireless information and power transfer (SWIPT) is considered as one of the novel
techniques to meet this demand. In this work, an adaptive power allocation scheme called
SWIPT based adaptive power allocation (SWIPT-APA-NOMA) is proposed for a power
domain NOMA network. The proposed scheme considers the receiver sensitivity of the
end users while calculating the power allocation coefficients in order to prevent wastage
of power allocated to user in outage and by offering priority to any one of the users to use… More >
