From: On the performance of an enhanced transmission scheme for cooperative relay networks with NOMA
The ergodic SRs achieved by our proposed CTRS-NOMA single case I, CTRS-NOMA single case II, CTRS-NOMA superposition case, and the TDMA scheme with fixed a1=c1=0.7, b1=0.3, \(\protect \phantom {\dot {i}\!}\alpha _{{SR}_{1}}=\alpha _{{SR}_{2}}=10\), \(\protect \phantom {\dot {i}\!}\alpha _{R_{1}D}=2\), and \(\protect \phantom {\dot {i}\!}\alpha _{R_{2}D}=\{10,40\}\) versus the transmission SNR
