Abstract - A crucial aspect in the world of communication is signal processing. Software Defined Radio makes it simple to comprehend and demonstrate real-time signal-processing ideas. The open-source programme GNU Radio, which serves as a simulation tool to drive the reception hardware, is the subject of this study. Here, RTL-SDR on/in GNU Radio is used to construct a wideband FM receiver. As a comparison to alternative gear, the suggested way of receiving signals using an RTL-SDR is more important and less expensive. Using RTL-SDR, Python, and GNU Radio, a low-cost experimental kit containing authentic radio signals from multiple sources is created. The information in this paper can be used to create CR systems that are trustworthy and usable in real-world settings.

Keywords – software-defined radio, GNU radio, RTL-SDR
