| Summary: | One of the most effective approaches to satisfying
the requirements of the next generation of wireless services is
non-orthogonal multiple access (NOMA). Spectrum efficiency and
average capacity are two aspects of wireless communication that
have become increasingly important as the number of mobile
services in use has increased. Using both traditional MIMO and
Massive MIMO (M-MIMO), this study proposes two new methods
for increasing the average capacity of a 5G network's downlink
(DL) NOMA power domain (PD) in conjunction with a
Cooperative Cognitive Radio Network (CCRN). The initial method
involves NOMA users competing for available rivalry channels
(R-CH) on the CCRN. The second technique creates a dedicated
channel (D-CH) for NOMA users. The MATLAB program is
utilized to evaluate the proposed methods in three scenarios with
varying distances, power location coefficients, and transmission
power. Successive interference cancellation (SIC) and unstable
channel conditions are also considered while assessing the
analysis of the proposed system under the assumption of Rayleigh
fading. Using DL NOMA PD systems, The results reveal that the
higher average capacity of best at transmit power
DL NOMA with CCRN (dedicated channel) improved U4 average
capacity performance by M-MIMO DL NOMA with
CCRN (D-CH) improved by when compared with
convention DL NOMA. Formulas in closed form were found for
average capacity. The resulting formulas are verified using a
Monte Carlo simulation |
