Abstract
In this paper, a spectrum sensing cognitive radio using the RTL-SDR interfaced with Simulink in MATLAB was developed. It performed spectrum sensing and signal prediction between the ranges of 25MHz to 1.5GHz, the tuner range of the RTL-SDR. The RF spectrum occupancy was explored by choosing specific centre frequencies between 25MHz to 1.5GHz in real time using the RTL-SDR. Tests were carried out in real time to ascertain the workability and efficiency of the RTL-SDR cognitive radio. The efficiency of the cognitive radio reduced as the false alarm probability increased. The cognitive radio’s efficiency also reduced in high noise signal floors.
