Abstract
A signal receiving method of a receiver includes the following steps. A time-domain received signal is transformed into a frequency-domain received signal, which includes multiple pilot symbols and multiple data symbols. Multiple channel impulse responses corresponding to the pilot symbols are estimated. Multiple inter-carrier interference and inter-block interference (ICIIBI) values corresponding to the pilot symbols are estimated based on the pilot symbols and the corresponding channel impulse responses. Multiple ICIIBI values corresponding to the data symbols are obtained via an interpolation operation according to the ICIIBI values corresponding to the pilot symbols. The estimated corresponding ICIIBI values are cancelled from the data symbols. The interference-cancelled data symbols are demapped to obtain soft-decision or hard-decision bits.
