<p>A frequency-division multiplexing transmission apparatus that transmits data at a frequency spectrum specific to a mobile station in which a À/4-continuous-phase-rotation unit (13) performs phase rotation that increases in increments of À/4 or decreases in decrements of -À/4 for each symbol of a transmission-symbol sequence; a symbol-repetition and rearrangement unit (14) compresses the time domains of each symbol of the transmission-symbol sequence after phase rotation, then repeats those symbols a specified number of times (L times), and rearranges the symbols of the obtained repetitive-symbol sequence so that it has the same arrangement as the original transmission-symbol sequence; a phase-rotation unit (15) performs phase rotation that changes at a speed specific to the mobile station for each symbol of the rearranged repetitive-symbol sequence; and a transmission unit (16) transmits the phase-rotated symbols.</p> |
