Cognitive Radio for Efficient Spectrum Utilization and Interference Management in RF Networks
Pratik Jangale · International Journal For Multidisciplinary Research · 2019
This paper explores how Cognitive Radio (CR) systems enhance spectrum utilization while effectively mitigating interference in RF networks. With increasing spectrum demands driven by 5G, IoT, and unlicensed access, interference management has become a important concern. CR technology dynamically senses, adapts, and optimizes available spectrum, enabling seamless coexistence across networks. We analyze CR-based techniques such as spectrum sensing, dynamic spectrum access (DSA), and self-optimization, and present real-world use cases involving LTE, 5G, IoT, and public safety networks. These examples demonstrate how CR improves spectrum efficiency and network reliability.
