Abstract

In this paper, we derive the throughput of non-orthogonal multiple access NOMA with adaptive transmit power for cognitive radio networks (CRN). The secondary source and relay adapt their power to not generate high interference at primary destination. We evaluate the packet error probability and the throughput at the packet level, while previous studies compute it at the symbol level. We also optimize the powers allocated to near and far users to maximize the throughput of CRN-NOMA. Besides, optimal power allocation of CRN-NOMA with adaptive transmit power has not been yet suggested and previous studies deal with fixed transmit power.
