Multipath Error Correction in Radio Interferometric Positioning Systems
1 Abstract—The radio interferometric positioning system (RIPS) is an accurate node localization method featuring a novel phase-based ranging process. Multipath is the limiting error source for RIPS in ground-deployed scenarios or indoor applications. There are four distinct channels involved in the ranging process for RIPS. Multipath reflections affect both the phase and amplitude of the rang...
متن کاملDistributed Radio Interferometric Calibration
Increasing data volumes delivered by a new generation of radio interferometers require computationally efficient and robust calibration algorithms. In this paper, we propose distributed calibration as a way of improving both computational cost as well as robustness in calibration. We exploit the data parallelism across frequency that is inherent in radio astronomical observations that are recor...
متن کاملPerformance Characterization of Positioning in LTE Systems
This paper presents low-level models of cellular LTE signals along with an architecture for a software-defined radio (SDR) that is capable of (1) extracting the essential parameters for navigation from the received LTE signals and (2) acquiring and tracking real LTE signals transmitted from multiple base stations. Moreover, a method for obtaining time-of-arrival (TOA) estimates that is highly r...
متن کاملRadio Interferometric Object Tracking
This paper proposes a novel object tracking method using radio interferometry. The proposed low cost solution is able to track objects, equipped with a radio receiver, in real time, using only simple infrastructure nodes with radio transceivers at fixed and known locations. The localization method has low computational requirements and does not require any preliminary knowledge of, or measureme...
متن کاملEnhanced Code Acquisition in Global Positioning Radio Systems
Satellite-based localization using the global positioning systems (GPS) has attracted ever growing attention in the last few years. In this work, we present a signal processing technique for initial code acquisition and synchronization of a GPS signal, such as the one used by position location techniques in 3G wireless scenarios. Several computer simulations have been accomplished to validate t...
