Research and Simulation on Pilot Configuration in Multi-antenna System Based on Kalman Filter
CRH has become a distinctive business card in the transportation industry around the world.However,transmitted signals suffer multi-path effect in wireless channels.Especially,server Doppler shift causes energy loss to received signals,and the wireless communication quality declines.In this paper,architecture of a joint Kalman Filter and multi-antenna system is designed,based on Ricean fading channels.A comparative analysis of channel performance estimation is given between the estimator designed by Ref.5 and that of our architecture by simulations.For the same velocity of the train and Ricean factor,DFO estimation error is less than the estimator mentioned before for the same number of received antennas.Then,we compare DFO estimation with pilots decreased by 10 in a frame according to previous assumptions of 50,simulation results show that,before the pilot number drops to 20,DFO estimation error has no obvious growth,when equals to 20,error increases significantly,that is,the estimation performance referred in this paper gets worse.Another important contribution for this paper is that the framework we have established provides a method and basis for the pilot configuration in a multi-antenna system to a receiver.
