ABSTRACT:
A transmission signal generating unit has a window function calculator that generates a window function that makes all frequencies without a center frequency of an input signal and its adjacent frequencies zero and makes the signal to noise ratio of the center frequency maximum; and a transmission signal generator that generates a transmission signal whose amplitude is modulated in a shape of an envelope curve based on the window function generated by the window function calculator.
