Analysis of Multipath Code-Range Errors in Future LEO-PNT Systems
Engineering Proceedings, 2023 In recent years, low-Earth-orbit (LEO) constellations have been proposed for Positioning, Navigation and Timing (PNT) applications. Moreover, a couple of test satellites have already been launched and many more are scheduled in the near future.

IEEE AccessWe investigated the propagation condition in a particular environment, such as an area covered by water or mud. In particular, we analyzed the effect on signal propagation in a fifth-generation (5G) wireless communication system in that scenario.

Multilevel MDA-Lite Paris Traceroute
, 2018 Since its introduction in 2006-2007, Paris Traceroute and its Multipath Detection Algorithm (MDA) have been used to conduct well over a billion IP level multipath route traces from platforms such as M-Lab.

A new multipath mitigation method for GNSS receivers based on antenna array [PDF]
, 2012 the potential of small antenna array for multipath mitigation in GNSS systems is considered in this paper. To discriminate the different incoming signals (Line of sight and multipaths), a new implementation of the well known SAGE algorithm is proposed ...

Metasurface‐Enabled Active‐Like Passive Radar
Advanced Science, EarlyView.A programmable space‐time‐coding metasurface embeds distinct spatiotemporal tags into ambient wireless signals, allowing passive radar to operate in an active‐like manner. By enabling code‐correlated reconstruction under interference, the approach supports robust real‐time UAV tracking in complex environments and points to intelligent, low‐power ...

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.

Performance evaluation of multipath transport protocol in heterogeneous network environments [PDF]
, 2012 Performance of multipath transport protocols is known to be sensitive to path asymmetry. The difference between each path in terms of bandwidth, delay and packet loss has a potential to significantly decrease the overall performance of a data flow ...

Multipath channels of unbounded capacity [PDF]
2008 IEEE 25th Convention of Electrical and Electronics Engineers in Israel, 2008 The capacity of discrete-time, non-coherent, multipath fading channels is considered. It is shown that if the delay spread is large in the sense that the variances of the path gains do not decay faster than geometrically, then capacity is bounded in the signal-to-noise ratio.
