The Influence of the Radio Channel on Precision of Position Estimation of the User Terminal Using the NB-IoT Radio Interface
Abstract
In the article the method of user terminal position estimation using the broadcast signals transmitted in the downlink of the NB-IoT interface was presented, including the analysis of the radio channel influence on precision of position estimation as well as the eNodeB (Evolved Node B) synchronization. The practical ability to estimate the position in the test area has been verified in the laboratory conditions, using the reference signals with a variable signal-to-noise ratio and different radio channel profiles. Additionally, the method that allows increasing the precision of the terminal position estimation without the need of increasing the sampling frequency of the radio signal is presented.
