Target Tracking in Small-Cell Mobile Networks

摘要

In this paper, we present the positioning schemes for the LTE small-cell mobile networks. Along with the development of next generation mobile communication network, the application of small-cell has become an important issue in cellular mobile networks. The accuracy of target positioning and location can be improved efficiently through small-cell mobile network. We use the observed time difference of arrival (OTDOA) positioning scheme to build cellular base station networks based on the Long Term Evolution (LTE) mobile communication network. The effects of geometric dilution of precision (GDOP) for OTDOA positioning and target tracking performance by using Kalman filtering were investigated. Computer simulation results of two different layouts of eNodeBs, staggered and non-staggered layout methods were included in our work.
