Abstract
Cognitive Radio (CR) has emerged as a groundbreaking technology in wireless communication, promising optimized use of the available spectrum. The crux of its efficiency lies in its spectrum sensing capabilities, which allow CR to detect vacant frequency bands dynamically. In order to enable spectrum sharing, spectrum sensing plays a crucial role in wireless communication. The challenges in wireless spectrum require collaboration among stakeholders to devise innovative solutions. This work delves into the fundamental techniques and challenges associated with spectrum sensing in CR systems, explores the use of CR system that employs a Time-Domain Symbol Cross-correlation (TDSC) based spectrum sensing algorithm. Worldwide Interoperability for Microwave Access (WiMAX) and Long-Term Evolution (LTE) standards are utilized as case studies to demonstrate the efficacy of the TDSC method. The study presents theoretical and simulation results and also suggests future research to investigate the performance of the TDSC method in WiMAX and LTE systems. Additionally, this study compares the spectrum sensing capabilities of WiMAX and LTE.

Keywords
