and converts the input signal is separated, separated into "00", "ll", "10", "00", "01 "and other data. Data separated further positive change modulation on the time axis are formed ,, Q amplitude components. These signals are in the IDFT inverse discrete Fourier transformation. Converted into, and Q signals respectively and / serial conversion and then outputs two orthogonal ,, Q serial signal.
