Abstract:
The invention relates to DVB-T system, and in particular, to a channel estimation method for OFDM symbols. A plurality of symbols are received to generate a pilot response. A finite impulse response is generated from the pilot response. A coefficient table is selected based on the characteristics of the finite impulse response. The channel is estimated by interpolating the pilot response based on the coefficient table.
