Abstract:
Wireless communications continue to see advancements from machine learning (ML) and artificial intelligence (AI). Typically, this is applied to individual components, attempting to add new capabilities, or enhance old ones. Little research has been done in the combination of these different components, to create a complete intelligent radio. This dissertation proposal aims to further the research of these components, and to combine these into an intelligent radio system. The proposed system intends to perform spectrum sensing, channel allocation, and software-defined transceiver signal processing, all enabled by ML. The goal of the design is to progress research into applying ML to these tasks in wireless systems. Specifically, Faster Region-based Convolutional Neural Network (FRCNN) along with open world learning will be leveraged in spectrum sensing and signal characterization. Multiple signals in cluttered RF environments will be simultaneously localized and characterized, including new-to-the-network signals by designing novelty detection and incremental learning using 1-D baseband raw data. The results of the spectrum sensing algorithm will be used to separate multiple signals in time domain. ML will be applied to enhance the signals by reducing channel effects. These enhanced signals are then demodulated using a deep learning approach. Finally, reinforcement learning is used to reconfigure the RF frontend, by allocating part of the wireless spectrum to transmit over. Such an intelligent radio system is anticipated to advance end-to-end communications, spectrum awareness, and electronic warfare.
