Kurzbeschreibung (Abstract)
This paper deals with semi-blind channel estimation in Single-Input Single-Output (SISO) Orthogonal Frequency Division Multiplexing (OFDM) communications system. The proposed algorithm proceeds in two main stages. The first one addresses the pilot-based Time-Of-Arrival (TOA) estimation using subspace methods and then estimates the channel through its specular model. In the second stage, one considers a decision feedback equalizer that is used to refine the channel parameters estimates. Simulation results show that good performance can be reached with only one OFDM pilot symbol with appropriate windowing using only one iteration. A significant performance improvement as compared to the pilot-based TOA method is observed.
