Abstract. The effective pilot-based channel estimation algorithms for mobile OFDM systems are grounded in this article. These algorithms are based on two-dimensional Wiener filtering and Kronecker type splitting of spaced-frequency spaced-time correlation function for wide-sense-stationary isotropic scattering channel model.

Key words: OFDM signals, pilot-based channel estimation, two-dimensional Wiener filtering, Kronecker type splitting.
