Patent ID: 8611444

Claim:
A receiver, comprising: a demodulation unit for transforming a time-domain received signal into a frequency-domain received signal that comprises a plurality of pilot symbols and a plurality of data symbols; a channel estimator for estimating a plurality of channel impulse responses corresponding to the pilot symbols; an inter-carrier interference and inter-block interference (ICIIBI) estimation unit for estimating a plurality of ICIIBI values corresponding to the pilot symbols based on the pilot symbols and the corresponding channel impulse responses; a finite impulse response filter for obtaining a plurality of ICIIBI values corresponding to the data symbols via an interpolation operation according to the ICIIBI values corresponding to the pilot symbols; an adder for cancelling the ICIIBI values corresponding to the data symbols from the data symbols; and a demapper for demapping the interference-cancelled data symbols to obtain estimation data corresponding to the time-domain received signal.
