A New Approach for Tracking Mobiles with Local Scattering Modeling
2000 (English)In: Proceedings European Signal Processing Conference, 2000Conference paper (Refereed)
A new approach for tracking mobiles in a multipath environment is presented. In this paper, we introduce the local scattering model into the tracking algorithm, which utilizes the linear approximation model, to improve the performance of DOA estimate in a multipath environment. The point of our method is to estimate the DOAs and the angular velocities of the mobiles simultaneously by minimizing a cost function, which is consist of the observed data. Moreover, the cost function takes into account of the scattering factor to cope with the multipath signals. The proposed method can estimate the DOA precisely without increasing much computation load. The efficiency of the method is shown through simulation results.
