GPS Multipath Detection Based on Carrier-to-Noise-Density Ratio Measurements from a Dual-Polarized Antenna
Sanghyun Kim, Halim Lee, Kwansik Park
In this study, the global positioning system (GPS) multipath detection was performed based on the carrier-to-noise-density ratio, C/N0, measured through a dual-polarized antenna. A…
Integrity-Based Path Planning Strategy for Urban Autonomous Vehicular Navigation Using GPS and Cellular Signals
Halim Lee, Jiwon Seo, Zaher M. Kassas
An integrity-based path planning strategy for autonomous ground vehicle (AGV) navigation in urban environments is developed. The vehicle is assumed to navigate by utilizing cellula…
RSS-based LTE Base Station Localization Using Single Receiver in Environment with Unknown Path-Loss Exponent
Suhui Jeong, Halim Lee, Taewon Kang +1
With the increasing demand for location-based services, localization technology research has recently intensified. Received signal strength (RSS)-based localization has the advanta…
A Preliminary Study of Machine-Learning-Based Ranging with LTE Channel Impulse Response in Multipath Environment
Halim Lee, Jiwon Seo
Alternative navigation technology to global navigation satellite systems (GNSSs) is required for unmanned ground vehicles (UGVs) in multipath environments (such as urban areas). In…
Neural Network-Based Ranging with LTE Channel Impulse Response for Localization in Indoor Environments
Halim Lee, Ali A. Abdallah, Jongmin Park +2
A neural network (NN)-based approach for indoor localization via cellular long-term evolution (LTE) signals is proposed. The approach estimates, from the channel impulse response (…
