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 \(\protect \phantom {\dot {i}\!}\alpha _{{SR}_{1}}=5\), \(\protect \phantom {\dot {i}\!}\alpha _{{SR}_{2}}=1\), \(\protect \phantom {\dot {i}\!}\alpha _{R_{1}D}=2\), \(\protect \phantom {\dot {i}\!}\alpha _{R_{2}D}=20\), b1=0.4, and a1=c1={0.6,0.8} versus the transmission SNR
