摘      要：In this article,we use Intelligent Reflecting Surfaces(IRS)to improve the throughput of Non Orthogonal Multiple Access(NOMA)with Adaptive Transmit Power(ATP).The results are valid for Cognitive Radio Networks(CRN)where secondary source adapts its power to generate low interference at primary *** all previous studies,IRS were implemented with fixed transmit power and previous results are not valid when the power of the secondary source is *** CRN,secondary nodes are allowed to transmit over the same band as primary users since they adapt their power to minimize the generated *** NOMA user has a subset of dedicated *** any NOMA user,all IRS reflections have the same ***-NOMA using IRS offers 7,13,20 dB gain ***-NOMAwithout IRS for N=8,16,32 *** also evaluate the effects of primary *** results are valid for any number of NOMA users,Quadrature Amplitude Modulation(QAM)and Rayleigh channels.
