Recent Trends in Interference Mitigation and Spoofing Detection

Fabio Dovis (Politecnico di Torino, Italy)
Luciano Musumeci (Politecnico di Torino, Italy)
Nicola Linty (Politecnico di Torino, Italy)
Marco Pini (Istituto Superiore Mario Boella, Italy)

This paper gives a classification of intentional and unintentional 
threats, such as interference, jamming and spoofing, and discusses some 
of the recent trends concerning techniques for their detection and 
mitigation. Despite the fact that these phenomena have been studied 
since the early stages of Global Positioning System (GPS), they were 
mainly addressed for military applications of Global Navigation 
Satellite Systems (GNSS). However, a wide range of recent civil 
applications related to user’s safety or featuring financial 
implications would be deeply affected by interfering or spoofing signals 
intentionally created. For such a reason, added value processing 
algorithms are being studied and designed, in order to improve accuracy 
and robustness of the receiver and to assure the reliability of the 
estimated position and time solution.

Challenges in Channel Measurement and Modeling for RF Localization 
Inside the Human Body

Kaveh Pahlavan (Worcester Polytechnic Institute, USA)
Yunxing Ye (Worcester Polytechnic Institute, USA)
Ruijun Fu (Worcester Polytechnic Institute, USA)
Umair Khan (Worcester Polytechnic Institute, USA)

In this invited paper, the authors introduce an overview of the 
fundamentals of radio frequency (RF) channel measurement and modeling 
techniques needed for localization inside the human body. To address 
these fundamentals, the authors use capsule endoscopy as an example 
application. The authors first provide the results of the Cramer Rao 
Lower Bound (CRLB) for received signal strength (RSS) based endoscopy 
capsule localization, inside the human body, using existing path-loss 
models for radio propagation. Then challenges demanding further research 
are highlighted for attaining more precise localization using the 
time-of-arrival (TOA) based ranging techniques.

Theoretical Analysis of Overlay GNSS Receiver Effects

Alexander Rügamer (Fraunhofer IIS, Germany)

Santiago Urquijo (Fraunhofer IIS, Germany)
Günter Rohmer (Fraunhofer IIS, Germany)

Having given a short overview of GNSS signals and state-of-the-art 
multi-band front-end architectures, this paper presents a novel 
contribution to efficient multi-band GNSS reception. A general overlay 
based front-end architecture is introduced that enables the joint 
reception of two signals broadcast in separate frequency bands, sharing 
just one common baseband stage. The consequences of this overlay are 
analyzed for both signal and noise components. Signal overlay is shown 
to have a negligible impact on signal quality. It is shown that the 
noise floor superposition results in non-negligible degradations. 
However, it is also demonstrated that these degradations can be 
minimized by judiciously setting the relative gain between the two 
signal paths. As an illustration, the analytical optimal path-control 
expression to combine overlaid signals in an ionospheric-free 
pseudorange is derived for both Cramér-Rao Lower Bound and practical 
code tracking parameters. Finally, some practical overlay receiver and 
path control aspects are discussed.

Motion Restricted Information Filter for Indoor Bluetooth Positioning

Liang Chen (Finnish Geodetic Institute, Finland)
Heidi Kuusniemi (Finnish Geodetic Institute, Finland)

Tuomo Kröger (Finnish Geodetic Institute, Finland)
Ruizhi Chen (Finnish Geodetic Institute, Finland)

This paper studies wireless positioning using a network of Bluetooth 
signals. Fingerprints of received signal strength indicators (RSSI) are 
used for localization. Due to the relatively long interval between the 
available consecutive Bluetooth signal strength measurements, the 
authors propose a method of information filtering with speed detection, 
which combines the estimation information from the RSSI measurements 
with the prior information from the motion model. Speed detection is 
further assisted to correct the outliers of position estimation. The 
field tests show that the new algorithm proposed applying information 
filter with speed detection improves the horizontal positioning accuracy 
of indoor navigation with about 17% compared to the static 
fingerprinting positioning method, achieving a 4.2 m positioning 
accuracy on the average, and about 16% improvement compared to the point 
Kalman filter.

A Simulation Tool for Real-Time Hybrid-Cooperative Positioning Algorithms

Francesco Sottile (Istituto Superiore Mario Boella, Italy)
Mauricio A. Caceres (Istituto Superiore Mario Boella, Italy)
Maurizio A. Spirito (Istituto Superiore Mario Boella, Italy)

The authors propose a simulation tool (ST) able to test real-time hybrid 
GNSS/terrestrial and cooperative positioning algorithms that fuse both 
pseudorange measurements from satellites and terrestrial range 
measurements based on radio frequency communication performed between 
nodes of a wireless network. In particular, the ST simulates devices 
belonging to a peer-to-peer (P2P) wireless network where peers, equipped 
also with a GNSS receiver, cooperate among them by exchanging aiding 
data in order to improve both positioning accuracy and availability. 
Furthermore, the authors propose a method to increase the robustness of 
cooperative algorithms based on the estimated position covariance 
matrix. In particular, the proposed approach assures a faster estimation 
convergence and improved accuracy while lowering computational 
complexity and network traffic. Finally, the authors tested the 
sensitivity of the implemented positioning algorithms through the ST in 
two different scenarios, first in presence of high level of pseudorange 
noise and then in presence of a malicious peer in the P2P network.
