Analysis of FPS and DPS in noma for real-time and non-real time applications under different mimo techniques

Abstract

In 5G wireless communication, Non-Orthogonal Multiple Access (NOMA) is a preferred approach for accommodating a large number of users while also providing significant capacity. The same data is sent to all users via a technique called cooperative relaying, and one user can relay data to another. Energy harvesting systems have been devised to provide enough power for users, with Simultaneous Wireless Information and Power Transfer (SWIPT) gaining popularity in recent years. A comparison of two different power allocation systems in NOMA, Fixed Power Allocation Scheme (FPS) and Dynamic Power Allocation Scheme (DPS), is presented in this work (DPS). The comparisons were developed based on how well they performed and what they were like while undergoing SWIPT. When compared to FPS, it has been discovered that employing DPS results in a nearly 25% boost in peak spectral efficiency. DPS, on the other hand, has a larger risk of outage since increased power causes the signal bandwidth to fall below the goal rate a substantial number of times. Conclusions were reached based on the comprehensive data as to which power allocation coefficient scheme will be employed in real-time and non-real-time communication standards. The findings imply that FPS is better for real-time communication, while DPS appears to work better for non-real-time communication. After incorporating MIMO techniques with NOMA, it was found that the system performed better for far users consistently. And for near users, MIMO performed better in high power region.
