Ranging Error Estimation in Indoor Environment at 10 GHz
Résumé
The aim of this paper is to model the radio channel behavior in indoor environment, and evaluate its impact on a ranging system by means of error estimation. The simulations were performed in a tunnel scenario at 10 GHz, and the ray tracing model was adopted to obtain the channel response. In the time-of-arrival based ranging system, the accuracy of distance estimation strongly depends on the system resolution, so we investigate the relationship between the error and the system bandwidth. Moreover, an optimal energy threshold was defined, since the simulated receiver is a non-coherent energy detector.
