Abstract

"Wireless devices are becoming increasingly pervasive across all aspects of society. Examples of such devices include radios, routers, mobile phones, tablets, and more. As the number of radio frequency (RF) devices continues to rise, so does the amount of interference and noise increase. This is why an efficient approach to interference detection is explored. Most research within this area has been done strictly within the frequency domain as viewing a signal within this domain provides many insights into what makes the signal. This has, however, led to the time domain being underutilized for this area of research.

To explore the time domain and its uses within radio frequency interference (RFI) detection we propose a lightweight program that requires knowledge of the known set of RF devices. The program utilizes a Long-Short Term Memory model to simulate a known radio set; it does this by training on a set of known signals interfered with each other. A custom statistical discriminator is then used to compare the simulated signal to the received signal. The output bounds of interference are then observed to determine how accurately our model detects and localizes interference" -- Abstract, p. iv
