A radio communication device capable of lightening the influence of a frequency selective fading in the wide-band transmission of a single carrier thereby to prevent deterioration of error rate characteristics. In this device, an FFT unit (13) subjects a modulated signal inputted from a modulation unit (12) to a Fourier transformation. A pilot insertion unit (14) inserts a pilot symbol into a plurality of individual frequency components (1-N) of the modulated signal. Weight multiplication units (15-1, 15-2) multiply the individual frequency components (1-N) and the pilot symbols inserted into the individual frequency components (1-N), by weight coefficients (W11-W1N, W21-W2N) set at a weight coefficient setting unit (54). IFFT units (16-1, 16-2) subject the frequency components (1-N) to an inverse Fourier transformation, thereby to convert the frequency components (1-N) into time domains.
