Abstract: A transmitter and the method therefor are provided. The transmitter is applied in an orthogonal frequency division multiplexing (OFDM) based or other multicarrier communication systems. The transmitter uses N sub-carriers. Among the N sub-carriers, L sub-carriers (or tones) are reserved for PAPR reduction. L is less than N. The method includes the following steps. Original frequency domain data symbols are generated and fed into the reserved-tone symbol generation unit. The reserved-tone symbols are generated by using pure frequency domain signal processing. Then the reserved-tone symbols are combined with original data symbols to generate combined PAPR reduction signal. The resultant PAPR reduction signal can be fed into reserved-tone symbol generation unit iteratively to obtain updated reserved-tone symbols. For proper iterations, the original data symbols combined with L frequency domain reserved-tone symbols will result in lower PAPR transmit signal.

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.
