Examples OFDM modulation system. Seen from the graph, the input data signal (... --- Ol01100), the data signal by the string,
Examples OFDM modulation system circuit - schematic

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.
