Employing Ray-Tracing and Least-Squares Support Vector Machines for Localisation
Blog Article
This article evaluates the use of least-squares support vector machines, with ray-traced data, to solve the problem of localisation in multipath environments.The schemes discussed concern 2-D localisation, but could easily be extended to 3-D.It does not require NLOS identification and mitigation, Nesting Tables hence, it can be applied in any environment.Some background details and a detailed experimental setup is provided.Comparisons with schemes that require NLOS identification and mitigation, from earlier work, are also presented.
The 2 Piece Sectional results demonstrate that the direct localisation scheme using least-squares support vector machine (the Direct method) achieves superior outage to TDOA and TOA/AOA for NLOS environments.TDOA has better outage in LOS environments.TOA/AOA performs better for an accepted outage probability of 20 percent or greater but as the outage probability lowers, the Direct method becomes better.
