Experimental Study on Quadrature Chaos Shift Keying Communication System

This study investigates the experimental implementation of the Quadrature Chaos Shift Keying (QCSK) communication system as a method to strengthen physical layer security in Internet of Things (IoT) communication. It highlights the critical function of chaotic oscillators in enhancing IoT security. A comprehensive analysis is provided, showcasing the potential of chaos oscillators in achieving reliable and secure data transmission. A QCSK communication system prototype using analog components was developed and evaluated experimentally to validate the system’s performance. The experimental setup included two configurations, emphasizing the importance of selecting appropriate signals for synchronization and information transfer. The system’s performance was measured using the bit error ratio as a key metric.
