Abstract—We propose a new scheme for pilot-symbol-aided
channel estimation in orthogonal frequency-division multiplexing
(OFDM) systems in multipath fading channels, that does not
require the knowledge of the channel statistics (e.g., Doppler or
power spectrum). It is based on using the radial basis function
(RBF) network to model the dynamics of the fading process.
Both one-dimensional and two-dimensional RBF networks are
proposed to exploit the channel correlation in the time domain
and in the time-frequency domain, respectively. The proposed
RBF networks are essentially nonlinear interpolators of the pilot
channels. Compared with the existing OFDM channel estimation
methods based on linear filtering, the proposed new techniques
offer both robustness to fading rate, and a better performance
especially in relatively fast fading channels.
