| description | Abstract This paper introduces a novel approach to enhancing spectrum sensing accuracy for 5G and LTE signals using advanced deep learning models, with a particular focus on the impact of systematic hyperparameter tuning. By leveraging state-of-the-art neural network architecture, namely DenseNet121 and InceptionV3—the study aims to overcome the limitations of traditional spectrum sensing methods in highly dynamic and noisy wireless environments. The research highlights that, through rigorous hyperparameter optimization, these models achieved substantial improvements in detection accuracy, reaching 97.3% and 98.2%, respectively, compared to initial performance levels of 93.0% and 95.0%. These performance improvements were particularly notable in controlled scenarios where low signal-to-noise ratio frames were excluded, with 60% of frames containing little or no information—highlighting the critical role of signal quality in both training and evaluation. It is worth noting that the models were trained and tested on a large and diverse dataset, including synthetic signals and real-world data, simulating a wide range of practical deployment conditions. This comprehensive database supports the generalizability of the proposed approach and its real-world applicability. The study also confirms that the models demonstrated competitive performance in various test scenarios, and that their integration into future wireless systems could significantly enhance smart spectrum management and real-time communication reliability in modern networks. |
