Popis:	This paper proposes a relaying scheme in an underlay cognitive radio network(CRN), where a source node desires to transmit the information simultaneously to more than two desired destinations. The power required for the relay operation is based on applying energy harvesting from the base station (BS). The proposed paper also includes Non-orthogonal multiple access (NOMA) with fixed power allocation to the different users to perform the decoding process irrespective of the channel condition. We have proposed a mathematical expression for the analysis of outage probability for the different users. In this respect, the linear model is discussed for perfect successive interference cancellation (SIC) at the receiver. Using the fixed power allocation process, we have simulated different output parameters such as Bit Error Rate (BER), NOMA capability, and the outage probability.
