Abstract
The increased use of wireless transmission has increased the demand for wireless radio spectrum, which can be used for a variety of social and individual benefits. As a result, radio spectrum allocation and utilization are also critical tasks. Cognitive Radio (CR) is a cutting-edge technology that claims to overcome this problem by allowing unlicensed users to access the radio spectrum without interfering with licensed users.Cognitive radio is a new technique that uses an intelligent Software Defined Radio (SDR) mechanism to assist manage the impending spectrum issue through dynamic spectrum allocation and accommodate growing data traffic. With the use of software defined protocols, SDR avoids frequent changes to the hardware structure.The key innovation of this study is the practical implementation of CR on GNU radio for real-time transmission as a primary user utilizing an energy-based spectrum sensing approach. The goal of this project is to develop a spectrum sensing approach that is best suited for detecting white spaces during SDR transmission.
