Exploring Spectrum Sensing Techniques in Cognitive Radio Systems Using Time-Domain Symbol Cross-correlation

Abstract

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 research explores the use of a Cognitive Radio (CR) system that employs a Time-Domain Symbol Cross-correlation (TDSC) based spectrum sensing algorithm. WiMAX and 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.
