DECODE: Exploiting Shadow Fading to DEtect COMoving Wireless DEvices

G. Chandrasekaran, M.A. Ergin, M. Gruteser, R.P. Martin, Jie Yang, Yingying Chen
2009 IEEE Transactions on Mobile Computing  
DECODE can not only be implemented in the position space but also in the signal space where a correlation in shadow fading due to objects blocking the path between the transmitter and receiver exists.  ...  The positioning errors from indoor RSS-based localization systems tend to be too large, making it difficult to detect whether two devices are moving together based on the interdevice distances.  ...  Our localization system relied on an existing signal map of the building, which discretizes spaces and contains an observed signal strength vector (each value corresponding to a different receiver) for  ...

Investigation of indoor localization with ambient FM radio stations

Andrei Popleteev, Venet Osmani, Oscar Mayora
2012 2012 IEEE International Conference on Pervasive Computing and Communications  
The de-facto standard for indoor positioning is based on Wi-Fi and while other localization alternatives exist, they either require expensive hardware or provide a low accuracy.  ...  While the outdoor location-aware services based on GPS are becoming increasingly popular, their proliferation to indoor environments is limited due to the lack of widely available indoor localization systems  ...  In contrast, Pearson's correlation coefficient implicitly considers both parameters of a linear fit and is less sensitive to eventual outliers, explaining the high performance of the correlation based  ...
