摘要：
In this paper we address the problem of channel and frequency offset estimation for Multiple-input Multiple-Output OFDM systems for mobile users. The proposed method stems from Extended Kalman filtering. It is suitable for time and frequency selective channels. The algorithm performs channel and offset tracking in time-domain followed by equalization in frequency domain. Simulation results demonstrating high fidelity tracking capability are presented using realistic channel model in typical urban scenarios.
