A radio communication apparatus includes a baseband signal generator to generate digital data; a clock generator to generate 2N pulse signals corresponding to the digital data; a selector to select one of the 2N pulse signals; and a short pulse generator to reduce a pulse width of the signal selected by the selector, wherein the 2N pulse signals include a whole-period non-transmission pulse, a whole-period transmission pulse, and 2N-2 partial-period transmission pulses, when the partial-period transmission pulse is selected, a band pass filter outputs a signal that lasts for part of a period having a 1-symbol length, when the whole-period non-transmission pulse is selected, the band pass filter outputs a signal attenuated by offsetting signals corresponding to the whole-period non-transmission pulse, and when the whole-period transmission pulse is selected, the band pass filter outputs a signal that lasts for a whole of the period having the 1-symbol length.
