Example of OFDM modulation system . As can be seen from the figure, the input data signal (...---Ol01100)
is serialized and converted to separate the input signal into "00", "ll", "10", "00", and "01" "Waiting for data.
    The separated data is then subjected to forward-varying modulation to form amplitude components of , and Q respectively on the time axis. These signals are subjected to
inverse discrete Fourier transformation in IDFT . After conversion, the Q signal and Q signal are converted to parallel/serial respectively, and then two orthogonal Q and Q serial signals are output .
