Anomaly Detection for Urban Vehicle GNSS Observation with a Hybrid Machine Learning System
Remote Sensing, 2020 In urban areas, the accuracy and reliability of global navigation satellite systems (GNSS) vehicle positioning decline due to substantial non-line-of-sight (NLOS) signals and multipath effects. Recently, positioning enhancement approaches with supervised

5G Positioning and Mapping With Diffuse Multipath [PDF]
IEEE Transactions on Wireless Communications, 2019 5G mmWave communication is useful for positioning due to the geometric connection between the propagation channel and the propagation environment. Channel estimation methods can exploit the resulting sparsity to estimate parameters (delay and angles) of ...

Online multipath convolutional coding for real-time transmission [PDF]
, 2012 Most of multipath multimedia streaming proposals use Forward Error Correction (FEC) approach to protect from packet losses. However, FEC does not sustain well burst of losses even when packets from a given FEC block are spread over multiple paths.
