Abstract
A wireless communication apparatus capable of enhancing the transmission efficiency, while maintaining a good BER characteristic. In this apparatus, a setting part () sets, based on the maximum delay amount of a delayed wave and also based on the expansion of impulse response of FDE, an FFT part () to establish an FFT section of Nc symbol, and also sets a selecting part () to establish a selection section of Nc−2M−Δ symbol that is shorter than the FFT section. The setting part () also sets the start points of FFT and selection sections established at this time for such timings that they are shifted by Nc−2M−Δ symbol from the start points of the FFT and selection sections previously established. It should be noted that the maximum delay amount of the delayed wave is Δ symbol, the expansion of impulse response of FDE is plus/minus M symbols, and the symbol block length is Nc.
