Orthogonal Frequency Division Multiple Access (OFDMA) has emerged as a cornerstone technology in modern wireless communication systems due to its ability to efficiently utilize spectrum resources. However, the dynamic nature of wireless environments demands robust spectrum sensing techniques to ensure efficient spectrum utilization and mitigate interference. The fundamentals of OFDMA and its significance in contemporary wireless network is initially discussed by offering high spectral efficiency, flexibility, and support for diverse services, making it a fundamental technology in standards such as LTE (Long-Term Evolution) and Wi-Fi. Its significance is expected to grow further with the deployment of 5G and beyond. This article presents a comprehensive analysis of Optimized energy detection-based spectrum sensing in OFDMA systems. Evaluated the system performance through simulation by considering parameters such as energy consumption, detection accuracy, and spectral efficiency. Finally, we provide insights into future research directions and emerging trends in spectrum sensing optimization for OFDMA systems, including cognitive radio networks, dynamic spectrum access, and fifth-generation (5G) wireless networks.
