DeepTxFinder: Multiple Transmitter Localization by Deep Learning in Crowdsourced Spectrum Sensing

Abstract: As the radio spectrum has become the bottleneck resource with increasing volume of mobile data and ultra-dense network deployments, it is crucial to use spectrum more flexibly in time, space, and frequency dimensions. However, higher efficiency in spectrum usage facilitated by flexible spectrum allocation comes with a cost, namely the increased complexity of spectrum monitoring and management. Identifying the transmitters is at the interest of particularly spectrum enforcement authorities to ensure that spectr… Show more

“…To further increase the source identification accuracy, the maximum likelihood ratio test can be re-peated multiple times as a sequential probability ratio test (SPRT) [239]. Recently, some preliminary work investigated the adoption of deep learning approaches to cope with the presence of very few crowdsensing nodes, especially when operating in harsh propagation environments [240].…”

“…Positioning and localization play a crucial role in both military and commercial communications. For example, as the quantity of consumer-focused wireless devices continue to grow, positioning and localization become increasingly useful in emergency and safety applications, such as search and rescue operations [45], [46].…”

“…A large pixel subarea could certainly lead to high localization errors, due to very coarse granularity. We can address this by using a "tiling" technique, wherein we divide the given area into tiles, represent each tile by 100×100 size image and use our localization techniques, and do some post-processing to handle crosstiling issues (e.g., [6] uses overlapping tiles and employs a voting scheme inside the overlapping tile area).…”

“…A straightforward representation that represents the TXs with locations is to just use an array of (x, y) elements where each (x, y) element is the location of a transmitter, as in [6]. However, this simple representation is less conducive to efficient model learning, as the representation moves away from spatial representation (by representing locations as positions in the image) to direct representation of locations by coordinate values.…”
