WebTo address this, a simulation-based comparative study between NOMA and orthogonal multiple access (OMA) techniques for mmWave massive multiple-input and multiple-output (MIMO) communications is presented with performance discussions and identifying technology gaps. WebOMA is achieved, and the corresponding individual rates for users 1 and 2 are used for OMA to ensure a fair comparison. B. Problem Formulation In [13], the authors prove that NOMA can achieve a larger sum rate than OMA by simply assigning the same power coefficients to both schemes. However, having a higher sum
WebMar 26, 2024 · Figure 2 shows strong and weak users rate comparison of MIMO–NOMA and MIMO–OMA. From figure, we can say that strong user is having more achievable rate in NOMA compare to OMA, whereas the weak user in NOMA system suffers due to its saturation in its data rate after a transmit power of 15 dBm which is the drawback of … WebFigure 3 shows the data rates for User 1 and 2 in OMA and NOMA networks, based on the Equations (1)- (4), defined previously. As shown, it is clear that the NOMA outperforms …
