A Comparative Analysis of BER Performance for NOMA in the Presence of Rayleigh Fading and Impulse Noise
Journal Title: International Journal of Innovations in Science and Technology - Year 2024, Vol 6, Issue 2
Abstract
Importance of Study: This research investigates the integration of wired and wireless communication in Smart Grid (SG) systems, addressing the challenges posed by impulse noise and the increasing demand for bandwidth. Novelty statement: The study explores the impact of impulse noise models on NonOrthogonal Multiple Access (NOMA) performance within fading environments, offering insights into optimizing bandwidth utilization in multi-user SG communication. Material and Method: Numerical simulations validate the derived closed form of the bit error rate (BER) equation, utilizing a NOMA downlink system. The performance parameters for assessing the effects of impulse noise in a Rayleigh fading channel include instantaneous signalto-noise ratio (SNR), bit error rate, disturbance ratio, and the trade-off between spectral efficiency and energy efficiency. Result and Discussion: The research reveals that NOMA demonstrates promising performance in SG communication despite the presence of impulse noise, with BER decreasing rapidly with increasing signal-to-noise ratio (SNR). The study highlights a performance tradeoff between impulse noise and fading, emphasizing the importance of accurate SNR levels for power allocation in NOMA systems. Concluding Remarks: This study contributes novel insights into the robustness of NOMA under realistic SG conditions, offering valuable implications for enhancing reliability and efficiency in SG communication infrastructure.
