Abstract

This paper investigates the channel estimation problem of Orthogonal Frequency Division Multiplexing (OFDM) systems in high-speed train environment. The OFDM channel in the high-speed train environment is modeled by using basis expansion model (BEM). The estimation problem of the channel impulse response and Doppler frequency offset are studied. In the simulation, the modeling performances of different bases are compared. The estimation results of the channel impulse response and Doppler frequency offset show the effectiveness of this method in the high-speed train environment.
