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.
