ENHANCING THE TWO-WAY COOPERATIVE NETWORK PERFORMANCE USING NOMA AND RELAY SELECTION
Main Article Content
To enhance network performance in cooperative communication, the relay selection methods have been used with significant effects. In this paper, we study two-way relay networks using the partial relay selection and non-orthogonal multiple access protocol (NOMA) with successive interference cancellation (SIC). In the paper, the investigated model includes two end-users in a transmission condition with high loss due to fading or obstacles so there is no direct transmistion line between them, their connectivity is only performed through a cluster of decode-forward (DF) relay in haft duplex mode (HD). We discuss and analyze the outage probability of system by selecting a relay with the greatest gain. Next, system performance is surveyed according to signal to noise ratio (SNR). Finally, mathematical expressions in the paper are verified by Monte-Carlo simulation method using Matlab.
