It consists in replacing part of the spreading code with a secret, cryptographically generated sequence, that is also provided to legitimate receivers, allowing them to verify the signal authenticity and integrity. Different techniques and formats have been proposed, yet their formulation is typically given as a particular solution, lacking proper generality.This paper aims at providing a unified general model for the design, description, evaluation and comparison of such techniques, introducing simple performance and security metrics, abstracting from the particular cryptographic mechanisms required to generate the sequences. We derive a way to optimize the trade-offs between security level and signal availability to receivers that do not know the modified code, and between security level and required cryptographic resources.We also propose a simpler mechanism that closely approaches the optimal trade-off, and show that it significantly outperforms existing and proposed techniques, especially in the typically considered performance range. Finally, we evaluate the robustness of the proposed schemes to a partial observation of the transmitted modified code by the attacker.","PeriodicalId":123786,"journal":{"name":"2020 International Conference on Localization and GNSS (ICL-GNSS)","volume":"41 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132015384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wearable applications can include activity-based health and fitness recommendations, location-based social networking, location-based gamification, among many others. With the growing opportunities for LBSs, it is expected that location privacy concerns will also increase significantly. Particularly, in opportunistic wireless networks based on device-to-device (D2D) connectivity, a user can request a higher level of control over own location privacy, which may result in more flexible permissions granted to wearable devices. This translates into the ability to perform location obfuscation to the desired degree when interacting with other wearables or service providers across the network. In this paper, we argue that specific errors in the disclosed location information feature two components: a measurement error inherent to the localization algorithm used by a wearable device and an intentional (or obfuscation) error that may be based on a trade-off between a particular LBS and a desired location privacy level. This work aims to study the trade-off between positioning accuracy and location information privacy in densely crowded scenarios by introducing two privacy-centric metrics.","PeriodicalId":123786,"journal":{"name":"2020 International Conference on Localization and GNSS (ICL-GNSS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129160836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Low-cost GNSS receivers are often used in a vehicular context as they provide a reasonable trade-off between affordability and accuracy. Especially in dense urban environments shadowing or Non-Line-of-Sight (NLOS) reception of GNSS signals can occur, degrading availability and positioning accuracy. In order to still meet given performance requirements, GNSS positioning is usually assisted by correction data or multisensor data fusion. Intelligent transportation systems (ITS) provide an interconnection between vehicles and infrastructure, whose radio propagation properties can furthermore be exploited as local transponder based augmentation systems. Depending on the types of provided information, different data fusion levels can be selected. In this paper, we provide a tight integration of GNSS pseudoranges and RF augmentation systems based on spatial map data given as a digital elevation model. The proposed method is evaluated using a dynamic simulation scenario analyzing previously surveyed as well as synthetically created heavy-tailed measurement error distributions.","PeriodicalId":123786,"journal":{"name":"2020 International Conference on Localization and GNSS (ICL-GNSS)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133348084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is especially true for the self-interference (SI) encountered in full-duplex (FD) radios, but also in the case of strong interference between co-located radios. However, unlike in FD radios, receivers co-located with interference sources do not typically have direct access to the transmitted interference. This work analyzes the performance of a digitally-assisted analog interference mitigation method and its implementation for the suppression of frequency-modulated (FM) interference before quantization in global navigation satellite system (GNSS) receivers that are co-located with interference sources. Over-the-air measurement results are presented that illustrate the effects of interference mitigation on GPS L1 and Galileo E1 reception in a commercial off-the-shelf GNSS receiver and a software-defined GNSS receiver. The analysis covers the effects of the interference mitigation on the radio frequency (RF) front-end, acquisition, tracking, and positioning stages.","PeriodicalId":123786,"journal":{"name":"2020 International Conference on Localization and GNSS (ICL-GNSS)","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127325871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ideally, a tracking channel should be able to adjust to both noisy and dynamic environments for optimal performance. Precision and robustness define the performance of the tracking. The difference between the square root of the Cramer-Rao bound (CRB) and the average tracking jitter at the discriminator’s output determines the precision of the tracking, whereas the speed of the response specifies the robustness of the tracking in high dynamic scenarios. The amount of operations required to implement a robust tracking technique indicates the complexity of the algorithm. The fast adaptive bandwidth, the fuzzy logic, and the loop-bandwidth control algorithm adaptive tracking techniques are first analyzed and evaluated in a software receiver. Second, these techniques are implemented in an open software interface GNSS hardware receiver for testing in simulated scenarios with real-world conditions. The scenarios represent different dynamics and noise cases. The results show the loop-bandwidth control algorithm’s advantage over adaptive loop-bandwidth techniques while preserving good tracking performance and low complexity.","PeriodicalId":123786,"journal":{"name":"2020 International Conference on Localization and GNSS (ICL-GNSS)","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121124992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
