The Application of Ray-tracing to Mobile Localization Using the Direction of Arrival and Received Signal Strength in Multipath Indoor Environments
نویسندگان
چکیده
This work presents a new indoor localization method based on the fingerprinting technique. The proposed method uses a ray-tracing model that provides information about multipath effects. This information is stored in a dataset during the first stage of the fingerprinting method. The direction of arrival (DOA) and received signal strength (RSS) are used in the fingerprinting technique as a hybrid system. The localization estimation is calculated while taking into account the Euclidian distance between the DOA and the RSS from each unknown position and the information of the fingerprints. Numerical calculations were performed to show the mean and the standard deviation of the estimated error.

Application of Ray-Tracing for the Mobile Localization using the Direction of Arrival and the Received Signal Strength
The problem of 3D-radiolocalization in indoor environments with Line Of Sight (LOS) and Non Line Of Sight (NLOS) conditions has been investigated in recent years. Many people in academia and industry are currently involved in the research and development of these kind of approaches. The aim of this communication is to find a simple method that decreases the errors due to the absence of LOS and ...

Determination of mobile localization with time of arrival (TOA) signal is a requirement in cellular mobile communication. In some of the previous methods, localization with non-line-of-sight (NLOS) paths can lead to large position error. Also for simplicity, in most simulations suppose non stationary actual environments as stationary. This paper proposes (residual test + recursive least square)...

Blind localization and tracking of mobile terminals in urban scenarios is an important requirement for offering new locationbased services, handling emergency cases of nonsubscribed users, public safety, countering IEDs, and so forth. In this context, we propose a track-before-detect scheme taking explicitly advantage of multipath propagation in an urban terrain by using a priori information ab...
