A Belief Propagation Algorithm for Multipath-Based SLAM [PDF]
IEEE Transactions on Wireless Communications, 2018 We present a simultaneous localization and mapping (SLAM) algorithm that is based on radio signals and the association of specular multipath components (MPCs) with geometric features. Especially in indoor scenarios, robust localization from radio signals

Dense multipath component polarization and wall attenuation at 1.35 GHz in an office environment [PDF]
, 2018 This paper presents an analysis of dense multipath components in office meeting rooms. Radio channel sounding measurements at 1.35 GHz were performed with transmitter and receiver in the same room (intra-room) and in adjacent rooms (inter-room). Specular

Real-Time Multipath Mitigation in Multi-GNSS Short Baseline Positioning via CNN-LSTM Method
Mathematical Problems in Engineering, 2021 Multipath is the main systematic error of the Global Navigation Satellite System (GNSS) short baseline positioning. Multipath cannot be eliminated by the double-differenced technique and is difficult to parameterize, which severely restrict the high ...

UTHM water quality classification based on sub index [PDF]
, 2020 River or stream at their source is unpolluted, but as water flow downstream, the river or lake is receiving point and non-point pollutant source. Ammoniacal nitrogen (NH3- N) and suspended solids (SS) strongly influences the dynamics of the dissolved ...

Fuzzy based load and energy aware multipath routing for mobile ad hoc networks [PDF]
, 2015 Routing is a challenging task in Mobile Ad hoc Networks (MANET) due to their dynamic topology and lack of central administration. As a consequence of un-predictable topology changes of such networks, routing protocols employed need to accurately capture ...

Edge decompositions of multigraphs into multi-2-paths [PDF]
Opuscula Mathematica, 2004 We establish the computational time complexity of the existence problem of a decomposition of an instance multigraph into isomorphic 3-vertex paths with multiple edges.

Intrinsic Identification and Mitigation of Multipath for Enhanced GNSS Positioning
Sensors, 2020 In global navigation satellite system (GNSS)-based positioning and applications, multipath is by far the most obstinate impact. To overcome paradoxical issues faced by current processing approaches for multipath, this paper employs an intrinsic method to

SRA: Fast Removal of General Multipath for ToF Sensors
, 2014 A major issue with Time of Flight sensors is the presence of multipath interference. We present Sparse Reflections Analysis (SRA), an algorithm for removing this interference which has two main advantages.
