Detecção e localização de interferências de rádio frequência com rádio definido por software de baixo custo

Abstract

Considering the growing demand for telecommunications devices, the need for an interferencefree radiofrequency environment becomes increasingly essential. This Final Project proposes the development of a system capable of identifying and locating radiofrequency (RF) interference using a low-cost software-defined radio (SDR). The aim is to develop a viable, accessible, and efficient solution that can accurately detect sources of interference, supporting the preservation of communication service quality and integrity. The project explores theoretical concepts of spectral analysis and energy detection, along with their implementation in low-cost SDRs, while also addressing their limitations and potential applications in realworld environments. The results demonstrate the technique’s effectiveness in both controlled and practical settings. The study concludes that the proposed project offers a cost-effective alternative for interference monitoring in wireless networks, with potential applications in commercial and industrial contexts.
