Noise Mitigation in Radio Signals Using Convolutional Neural Network Autoencoders
摘要
This paper suggests a deep-learning approach for radio signal denoising using a Convolutional Autoencoder. It provides a basic understanding of machine learning and how it can mitigate the unnecessary noise from a radio signal. It can be trained specifically for a single kind of signal or combined can be used as a component of a denoising module in a pipeline. We have conducted tests and training on artificial radio data generated using mathematical functions and introduced different noise functions to mimic real world scenarios. Artificial radio data provides the freedom of flexibility to change different signal parameters and experiment on it using an autoencoder. Autoencoder can further be used to classify noise, protocol and modulation to improve the accuracy for denoising.
