A Comprehensive Survey of Machine Learning Based Localization with Wireless Signals

Daoud Burghal,
Ashwin T. Ravi,
Varun Rao
et al.

Abstract: The last few decades have witnessed a growing interest in location-based services. Using localization systems based on Radio Frequency (RF) signals has proven its efficacy for both indoor and outdoor applications. However, challenges remain with respect to both complexity and accuracy of such systems. Machine Learning (ML) is one of the most promising methods for mitigating these problems, as ML (especially deep learning) offers powerful practical data-driven tools that can be integrated into localization syst… Show more

“…However, this category can only perform data preprocessing, and location information cannot be obtained. [38]- [40], [42], [209], [210]. In summary, despite the channel at THz frequencies being more deterministic than at lower frequencies, which suits geometry-based methods well, we argue that learning-based methods still have advantages in two aspects.…”

“…In terms of localization, a number of surveys exist and share the localization basics and performance metrics in common. However, their goals are totally different and their main focuses can be categorized based on the environment (indoor [32], [35], [39], [41], outdoor [2], [33], [44] or both), techniques (SLAM [2], MDS [36], machine learning (ML) [38]- [40], etc. ), and signal types (radio signal [5], [6], visible light [9], RFID [41], etc.).…”

“…But with the development of multiantenna techniques and the computing power of the devices, more and more channel information can be obtained during communications. The contribution of the channel information to the localization/positioning has been extensively investigated [127]. According to the existing studies, the propagation environment impacts on the localization/positioning accuracy significantly.…”
