Analysis of throughput and error rate of 16-QAM, 64-QAM, and 256-QAM O-NOMA waveforms

Abstract

This study presents a comprehensive analysis of the throughput performance, spectrum efficiency, and block error rate (BLER) of optical non-orthogonal multiple access (O-NOMA) waveforms using 16-quadrature amplitude modulation (QAM), 64-QAM, and 256-QAM modulation schemes. The aim is to assess the trade-offs between data rate, spectral efficiency, and error performance in O-NOMA systems. The analysis reveals that higher-order modulations, such as 64-QAM and 256-QAM, offer higher data rates and improved spectrum efficiency compared to 16-QAM. Furthermore, the study investigates the spectrum performance of the O-NOMA waveforms. The results indicate that higher-order modulations may utilise the spectrum more efficiently, maximising the data throughput within the available bandwidth. Moreover, the BLER analysis provides insights into the error performance of the O-NOMA waveforms. It quantifies the probability of errors occurring in a block of transmitted data and evaluates the system’s reliability. The analysis reveals that 256-QAM O-NOMA achieves lower BLER and high throughput in uplink and downlink as compared with the 16 and 64-QAM O-NOMA frameworks.

Ad hoc wireless network implementing BEE-LEACH

“…These values for BEE-LEACH will be compared to values for traditional LEACH to show emphasis on battery life extension. Both networks will be identical and will be constructed in MATLAB using a random generation model [25].…”

PAPR reduction using SLM-PTS-CT hybrid PAPR method for optical NOMA waveform

“…However, O-NOMA also faces some challenges. One of the main challenges is the complexity of the receiver's successive interference cancellation processes, especially when dealing with a large number of users [ 36 ]. Efficient algorithms and signal processing techniques are required to handle the interference cancellation effectively.…”
