Abstract: An approach for indoor localization using cellular long-term evolution (LTE) carrier phase measurements, which mitigates multipath is developed. The proposed approach exploits the motion of the receiver to synthesize an antenna array from time-separated elements. The synthesized data received by the synthetic antenna array is processed to suppress multipath via determining the direction-of-arrival (DOA) of incoming LTE signals. The proposed LTESAN framework is validated experimentally and compared with a standalone LTE receiver, in which the pedestrianmounted receiver navigated 126.8 m indoors in 100 seconds, while receiving LTE signals from 6 eNodeBs. The proposed approach exhibited a position root mean-squared error (RMSE) of 3.93 m compared to 7.19 m using the standalone LTE receiver.
