Using FPGAs for Spectrum Sensing and Modulation Recognition

Project Objective

This project seeks to use machine learning to recognize different wireless devices. The project will use software defined radios (SDR) to record various devices, such as iphones, bluetooth earbuds, and Wifi laptops. These recordings will become the training data to a set of neural networks. The second part of the project will quantify the accuracy of the neural networks in classifying various device types based on their RF signatures.
