ABSTRACT:
An efficient channel estimation system and method provides good performance under high Doppler conditions and is suitable for OFDM systems such as DVB-T. A number of different pilot interpolations techniques enable the estimation of channel for the OFDM systems. For 2kand 4kmodes, the channel is estimated using the preceding symbol, the present symbol, and two succeeding symbols. For an 8kmode, only one future symbol is used to estimate the channel.
