The problem of channel estimation for Orthogonal
Frequency Division Multiplexing (OFDM) systems in fast timevarying
and frequency selective radio channels has attracted the
attention of scientists and receiver manufacturers. The wireless
communication suffers from Additive White Gaussian Noise
(AWGN), fading due to the multipath nature of the channel and
spectral dispersion caused by the relative movement of the
receiver with respect to the transmitter. In this paper a novel
channel estimator for the Next Generation Terrestrial Digital
Video Broadcasting (DVB-T2) is proposed. It is based on the
estimation of the Doppler Shift (DS) from the variations of the
envelope of the edge pilots (EP), in order to estimate the time
interval where the channel could be considered as flat and then
adaptively adjusting a buffer where the scattered pilots (ScP)
carried within the received OFDM symbols during this time
interval, are stored and averaged. Because the noise is considered
AWGN with zero mean, the averaging process discards the noise
and by interpolating the pilots an estimation of the channel is
