Wireless technique classification (WTC) is of crucial importance in Internet of Things for realizing efficient spectrum sharing and interference management. However, the existing deep learning-based methods have low classification accuracy, especially at low SNR levels. In this paper, a multi-scale convolutional neural network framework is proposed for WTC. A multi-scale module is exploited to capture the higher abstraction features. Simulation results demonstrate that our proposed scheme can achieve a better classification performance and a higher convergence speed compared to the state-of-the-art schemes.
