Abstract:
Due to massive connectivity and increasing demands of various services a
full-scale implementation of the fifth generation (5G) wireless systems requires
more effective radio access techniques. One of the major concerns of
5G networks is improved spectral efficiency. With reduced interference and
increased capacity, it needs high information rate. Non Orthogonal Multiple
Access (NOMA) is one of the competitive multiple access schemes over Orthogonal
Multiple Access(OMA) schemes in the previous generation for the
introduction of 5 G wireless networks. This thesis concerns with the performance
of mutiple access in Millimeter Wave in 5G.The large amount of
spectrum available at mmWave frequencies combined with a more effective
use of available resources, helps improving the overall capacity. Another major
issue is that the spectral efficiency and fairness are still open problems for
Orthogonal Multiple Access OMA, which lead to open the investigation and
evaluation of Non Orthogonal Multiple Access NOMA schemes. In this thesis,
we focus on comparison between OMA and NOMA schemes is presented with
consideration of mmWave propagation channel, the comparison is carried out
using MATLAB simulation based modeling, and performance metrics used
are channel capacity, SNR, Spectral Efficiency, and Energy Efficiency. And
from the simulation results introduced its clear to say that NOMA scheme is
a promising technology that can introduce further development in mmWave
according to its performance versus OMA.
