|Abstract:||A receiver for positioning with LTE signals, which could mitigate multipath in a computationally efficient fashion is presented. The receiver uses an orthogonal frequency division multiplexing (OFDM)–based delay-locked loop (DLL) to track the received LTE signals. The ranging error performance in an additive white Gaussian noise (AWGN) channel is evaluated numerically. The results demonstrate robust and accurate performance for high transmission LTE bandwidths. The proposed receiver is evaluated on a ground vehicle in an urban environment. Experimental results show a root mean squared error (RMSE) of 5.36 m, a standard deviation of 2.54 m, and a maximum error of 12.97 m between the proposed LTE receiver and the GPS navigation solution over a 1.44 Km trajectory. The robustness of the obtained pseudoranges with the proposed receiver are demonstrated against two algorithms: estimation of signal parameters by rotational invariance techniques (ESPRIT) and EKAT (ESPRIT and Kalman filter).|
