Abstract :
During the past few years, accurate positioning of terminals has received much attention in wireless communication. One reason is that of the requirement for emergency call positioning imposed by the authorities. The positioning algorithms based on the Navstar satellites have limitations in the indoor environment because the signal experiences severe attenuation in the indoor environment. The characteristics of the indoor propagation is still not well understood. In many cases, it is assumed that with the deployment of pseudolites, indoor navigation can show better performance. In this paper we analyze the indoor channel propagation using pseudolites, based on the measurement data collected in different scenarios.
